This study takes the digital campus construction planning of the high school as an example and determines the requirements ofthe postgraduate management information system under the digital campus environment through the analysis of the overallframework and technology of the digital campus. Combining the current situation of computer technology, networktechnology, and the actual situation of our university, the current mainstream B/S three-layer architecture is adopted, the webadopts the current popular Java Server Pages technology, and the struts framework connects to the Oracle backend databasethrough the Java Database Connectivity interface to design the browser-side and server-side programs. The struts frameworkconnects to the Oracle backend database through the Java Database Connectivity interface to design browser-side and server-side programs. The functional model and data flow model of the system were established through a detailed and effectiveanalysis of the entire workflow of postgraduate students’ training management during their school years. Then, the systemanalysis, design, and drawing of the swim lane diagram and data business flow diagram were carried out. The system wasdesigned in detail in terms of system architecture, development tools, functional modules, and database design, and the coremodule of training program making in postgraduate training management was highlighted as an example to discuss theprinciples and methods in the construction of departmental business systems and informatization under the digital campusenvironment, and a flexible and efficient postgraduate management information system was realized. It standardizes theconstruction of data standardization in universities; does a good job of standardizing and normalizing information; improvesthe accuracy, validity, and real-time production of data collection and the real and safe unified management of historical data;and provides scientific and reasonable data support for the leadership to make relevant decisions.

1. Introduction

With the deepening of education reform, the scale of postgrad-uate enrollment has been expanding, and the data to berecorded and processed in the training management work hasincreased exponentially. To standardize management andimprove the level and efficiency of postgraduate training man-agement, many universities have established postgraduate man-agement systems and related teaching support platforms oneafter another to realize the collection, processing, and statisticalfunctions of basic teaching information, which reduces themanual processing work of management personnel, improvesthe working efficiency, and brings great convenience to teachers

and students of the whole university [1]. It reduces the manualwork of management staff, improves work efficiency, andbrings great convenience to the teachers and students of theschool. However, from the perspective of the developmenttrend of graduate education and teaching, there are still someunsuitable places in the informatization of graduate studentsin colleges and universities. However, from the perspective ofthe development trend of postgraduate education and teaching,there are still some unsuitable places for postgraduate informa-tization in colleges and universities, mainly in the followingaspects: many postgraduate systems in colleges and universitieswere built earlier; the system construction did not follow thenational standards and industry standards; the data structure

and data content were not standardized; it is difficult to ensurethe consistency of data, resulting in difficulties in informationand data sharing between systems; and it is difficult to achievean upgrade and maintenance of the system [2]. Many schoolsdo not include the construction of graduate education informa-tization into a purposeful, planned, and step-by-step systemengineering project, and even if there is a better hardware andsoftware environment, it is difficult to mobilize most teachersand students to participate in the construction of educationinformatization to the greatest extent due to the lack of a corre-sponding standardized system and standardized management[3]. Many systems are designed from the needs of administra-tors, only designing management functions, with less supportfor cultivation management closely related to students’ learningactivities, which cannot support the whole process of graduatestudents’ learning activities, making it difficult for administra-tors to track and monitor the completion and quality of gradu-ate students’ studies and ensure the smooth progress of researchwork [4]. After collecting a lot of teaching information into thesystem, it only does simple query and statistical functions with-out deep processing and lacks multidimensional statistical anal-ysis functions, which makes it difficult to provide managementdecision analysis information to school leaders and managers.

This study intends to draw on the development experi-ence of other perfect systems, compare the more popularsystem development technologies, analyze the specific needsof the postgraduate training process in the light of the overallconstruction of our university digital campus, and share thedata information of other systems in the digital campusthrough the data exchange and sharing platform. For exam-ple, the personnel information in the personnel system, thefinancial information in the financial system, the undergrad-uate major course information in the teaching service sys-tem, and the student accommodation information in thecoordination management system, etc., to design a set ofmanagement information system suitable for the actual situ-ation of postgraduate management. However, due to the lackof a corresponding standardized system and standardizedmanagement, it is difficult to mobilize teachers and studentsto devote themselves to the construction of educationalinformation. Many system designs are based on the needsof managers, only designing management functions, andthere is little support for training management that is closelyrelated to student learning activities. It integrates variousheterogeneous data in the digital campus, unifies the man-agement of semistructured and structured data, eliminatesinformation silos, and realizes real-time data sharing amongsystems [5]. For example, it provides authoritative data suchas basic information of graduate students, cultivation, anddegrees for the data sharing center; it extracts basic informa-tion of faculty personnel and additional information such aspayment and accommodation of graduate students from thedata sharing center, which ensures the consistency of data[6]. Before the design and architecture of the system, a pro-spective study on the data standards of the university wasconducted, and the coding rules of human, financial, andmaterial aspects were planned uniformly from the univer-sity, which laid a good foundation for the construction ofthe data sharing center in our university. In the design pro-

cess of the postgraduate management information system, itis designed to exchange data from the digital campus shareddata platform and reserve the data interface for public infor-mation calling from the university’s portal or other systemscalling. For example, the integrated coding rules for person-nel information from students to faculty members can pro-vide a reference for the development of subsequent systemsby eliminating data cleaning, transcoding, and filtering forthe personnel database in the later stage.

It proposes the J2EE development platform of the aca-demic affairs network management system; introduces indetail the digitalized resource construction, student aca-demic supervision, and effective control, assessment ofteachers’ teaching and students’ learning, and student filemanagement modules of the university; and proposes howto optimize the functions of the information-based academicaffairs network management system for the paper focuses onthe digital campus teaching and learning management ofuniversities. This paper focuses on the design and imple-mentation of the digital campus academic affairs manage-ment system of colleges and universities and analyzes anddiscusses each functional module in the digital campus aca-demic affairs management system of colleges and universi-ties, which has a certain innovative value and has certainreference significance for the development of the digitalcampus academic affairs management system of other col-leges and universities. In addition, computers can be usedto select elective subjects for college teaching and carry outteaching assessments, which greatly saves the work pressureand work content of administrative teaching staff. Computernetwork technology allows each student to choose electivesubjects independently through the computer, which pro-vides sufficient autonomy for students and greatly improveswork efficiency, allowing teaching staff to have more time todeal with other things and meet the needs of students at dif-ferent stages.

2. Current Status of Research

Although the current university networked teaching man-agement model has improved, it still lacks a lot of rationalityand humanized design. Based on the above considerations,the development of an artificial intelligence-driven teachingmanagement information system suitable for various needsis particularly important for improving the efficiency andquality of managers and enhancing the image of the school[7]. For example, the British scholar Aithal and others men-tioned that some institutions in the UK and France havebuilt information technology earlier, and each universityfocuses on the construction of a web platform in the aca-demic affairs network management system [8]. Throughdecades of development, they already have a perfect andmature teaching system, teaching service system, office sys-tem, library system, campus entertainment system, and soon [9]. These system platforms have had a great impact onstudents, teachers, administrators, and community residents,facilitating students’ spare time, improving office efficiency,improving learning environment and methods, and acceler-ating the pace of transformation of an information-based

society [10]. The digital campus is better than UEAS Aca-demic Affairs Management System, which combines theadvantages of both and builds a better application system,deploying C/S computing mode for parts that need a lot ofcalculations, such as data import and data analysis, andB/S computing mode for parts that do not need too manycalculations, such as information query and display [11].The C/S computing mode is open to a few users who needit, and the B/S computing mode is developed for all usersof the system [12].

Many schools have established student informationmanagement systems, which provide a solid foundation formodern network education. The technical aspect of themanagement information system led to innovation andreform of the traditional office model, thus creating a previ-ously unavailable, new form of efficient modern office model[13]. As we all know, for the long-term sustainable develop-ment of each enterprise, there is a need for an efficient andconvenient management system; they will mostly choosereliable public generally recognized software companies tocooperate in the development, but the required developmentcosts and maintenance costs will become very difficult tobear, which for the market users, will be a cost-effectiveautomated management information system [14]. Thispaper will design and study the most cost-effective manage-ment information system to meet this demand [15]. In theinitial stage, the construction of information technology inuniversities only stopped at the registration and storage ofdata and only established a relatively closed local networkon campus, and the individuals who used this network onlyused it in the local area network, and with the improvementof requirements, the university built a medium-sized campusnetwork, which improved the efficiency of using the campusnetwork and accelerated the improvement of teaching qual-ity to a certain extent [16]. A large information center wasbuilt, and from the initial embryonic stage to the presentday, a complete information system has been built, whichhas greatly improved the degree of digitalization of theschool [17]. From the failed cases, we summarized whereits shortcomings lie and developed a student managementsystem suitable for education according to our characteris-tics [18]. At present, all major universities have built andimproved their campus networks, and the investment inhardware has taken shape, slowly entering the middle stageof the information technology era.

Based on ensuring information security, it is registeredand published on the school’s unified application platformto realize the sharing of information results within theschool, and on this basis, it is integrated with Internet appli-cations. The supply of highly experienced application ser-vices and integrated access to services to students greatlyincreases the dependability of users. With integrated servicescentered on high usage, campus faculty and students can notonly enjoy the services provided by the integrated serviceplatform but also provide their own opinions on problematiccampus facilities or campus services that need to beimproved, supporting decision-makers at all levels toimprove and study business models. The test cases of somefunctions of the digital campus teaching management sys-

tem are explained. The key involves book lending test cases,user login test cases, grade retrieval test cases, adding aca-demic records test cases, and specific descriptions of the sys-tem performance tests.

3. Analysis of Integrated Design of InformationSystem for Graduate Education in DigitalCampus Universities

3.1. Technical Analysis of Graduate Student EducationInformation System. The system uses an on-demand B/Stechnology architecture. This system also uses a J2EE-based development framework and runtime environmentto maximize the inclusion and integration of existing andto-be-built applications [19]. For example, provide the datasharing center with authoritative data such as basic informa-tion, training, and degrees of graduate students; extract basicinformation about teachers and workers from the data shar-ing center; and additional information such as postgraduatepayment and accommodation to ensure the consistency ofthe data. The SOA service-oriented architecture simplifiesthe processing mode of business process integration betweensystems, simplifies the difficulty of cross-system interfaceintegration due to changes in business requirements, andachieves loose coupling between systems [19]. The Oracledatabase with excellent performance is selected as powerful.A distributed software architecture is used to realize the inte-gration of data, services, and business processes utilizingapplication integration, and the digital campus is built insteps under a unified top-level design. Each system operatesindependently, and cross-system invocation and collabora-tion are realized through standard and clear interfaces.

The server is usually a high-performance PC, worksta-tion, or minicomputer with a large database system such asOracle or SQL Server. The B/S architecture has three maincomponents: client browser, application publishing server,and database server, as shown in Figure 1.

The construction of a digital campus is a long-term andcontinuous construction process that matches the strategy ofthe university. It is necessary to consider the results and dataof the university’s existing information technology construc-tion, and at the same time, it is necessary to lay the founda-tion and indicate the direction for the future development ofthe university’s information technology, so that the con-struction of the digital campus is a continuous improvementand continuous updating process over time and can effec-tively form the long-term accumulation of the university[20]. It does not break with the passage of time, changes intechnology, changes in management personnel, and changesin thinking. Digital campus construction is to provideadvanced and comprehensive informatization solutions foruniversities to build their core competitiveness throughinternal resource integration and accumulation of existinginformatization construction achievements. Digital resourceconstruction, student academic supervision and effectivecontrol, teacher teaching and student learning evaluation,student file management, and other modules propose howto optimize the functions of the information-based

educational administration network management systemand provide for the sustainable development of universityeducational administration network management referenceeffect. It guides the construction of a digital campus by for-mulating a long-term informatization construction plan ofthe university, comprehensively constructing university-level management information system, optimizing existingmanagement process and management mechanisms, improv-ing administrative management efficiency, and saving man-agement cost of the university while ensuring the realizationof strategic objectives of the university. Strengthen the con-struction of a basic support environment to ensure the safe,stable, and reliable operation of the system; build the basicplatform of digital campus based on the construction frame-work of “hardware cluster, data concentration, applicationintegration, and service integration.” Optimize the means ofcollaboration among personnel at all levels of colleges anduniversities, create a life service platform, teaching service plat-form, and scientific research service platform, and build acomprehensive digital campus service platform for teachers,students, and staff [21]. It standardizes the construction ofdata standardization in colleges and universities; standardizesand unifies the information; improves the accuracy, validity,and real-time of production data collection and the real andsafe unified management of historical data; and provides sci-entific and reasonable data support for the leadership to makerelevant decisions.

In the era of information technology, the education man-agement of colleges and universities is also facing greater chal-lenges. The construction andmanagement of digital campuses

in colleges and universities are the primary factor affecting thecontinuous improvement of the quality of education andteaching in colleges and universities [22]. In Huizhou Engi-neering Vocational College, the college proposes to pay atten-tion to the construction of a digital campus network system,and in the teaching-centeredmode, it is necessary to guaranteegood teaching quality and good teachingmechanism, preciselyfor the establishment of the current higher vocational collegeat the early stage, to establish an integrated working systemplatform, which has more efficient work efficiency comparedwith the traditional campus management and can also servethe teaching staff and students accurately [23]. It allows datato generate more shared value and establishes a data intervisit-ing mechanism. Focusing on on-campus information applica-tions, it solves various current management problems andserves campus faculty and students. This paper focuses onthe design and implementation of the digital campus academicaffairs management system of colleges and universities andanalyzes and discusses each functional module in the digitalcampus academic affairs management system of colleges anduniversities, which has a certain innovative value.

Many colleges and universities implement the manage-ment mode of large academic affairs and put all the workrelated to education and teaching into academic affairs, sowhether the school’s academic affairs management issmooth and the quality of academic affairs management isdirectly related to the quality of education and teaching. Inrecent years, Huizhou Engineering Vocational College hasbeen upgraded to a higher vocational college by mergingseveral secondary schools, and the management mode needs

to be changed continuously. At the same time, as the collegecontinues to expand and transform, the academic adminis-tration will also face increased pressure. To maximize theinclusion and integration of existing and to-be-built applica-tions, through the SOA service-oriented architecture, it sim-plifies the processing mode of business process integrationbetween systems, simplifies the difficulty of cross-systeminterface integration due to changes in business require-ments, and realizes loose coupling between systems. Toadapt to the changing needs of academic affairs manage-ment, the traditional manual work can no longer meet theneeds of complex academic affairs information manage-ment, which requires us to change our concept and adoptmodern means to manage the current academic affairs infor-mation and continuously improve the management of aca-demic affairs management for all teachers and students ofthe school, as shown in Figure 2.

The construction of a digital campus requires the schoolto establish its own data code rules, and to the maximumextent consistent with the education management informati-zation standard (Ministry of Education), relevant nationalstandards, and relevant industry-standard codes, reducethe duplication of code usage, and consider the need forfuture code expansion for the construction and maintenanceof code rules, i.e., school-defined data standard rules. Thedatabase server adopts a minicomputer system, and throughphysical partitioning technology, the informatization cam-pus database and the one-card database are run separatelyin different partitions, while a separate partition is used asthe environment for database testing and development. It

is planned to add a set of disk array systems with the sameconfiguration as the main storage system in the offsite serverroom as the offsite disaster recovery center and realize thesynchronous or asynchronous partial or complete replica-tion of data from the main storage center to the disasterrecovery center through the configuration of fiber opticswitch plus long-distance transmission interface moduleand data mirroring software.

The application servers are recommended to use Web-Sphere distributed load balancing deployment architectureand the entire deployment. The outermost layer is a dedi-cated hardware load-balancing device and can be deployedas a dual-computer active-active high availability mode,which is responsible for providing load balancing and highavailability guarantee for HTTP (80) traffic from users tothe HTTP front-end server; the middle is two WebSphereHTTP servers, which act as task schedulers for the back-end. These two HTTP front-end servers function as taskschedulers of the information portal platform and digitalcampus application servers at the back-end and are respon-sible for providing load balancing and high availability foruser requests to access the information portal and applica-tion systems at the back-end; the back-end is a WebSphereApplication Server Cluster member server. The constructionof the digital campus is a process of continuous improve-ment and renewal over time, which can effectively formthe long-term accumulation of the school. It does not leadto a break with the passage of time, technological develop-ment and changes, changes in management personnel, andchanges in thinking.

The graduate school and colleges determine whichcourses need to be offered each semester according to thecultivation program and calculate the number of requiredand elective courses according to the student cultivation pro-gram and provide comprehensive inquiries of course informa-tion, output, and print course statistics, and other functions.The graduate school and all colleges adopt the computer-aided manual scheduling method according to the coursesalready offered in the current semester to determine theteachers, time, and location of each course, and the systemprovides strict conflict verification of teachers and classroomresources and provides automatic generation and query func-tions of the curriculum. Students can be scheduled manuallyduring the scheduling process, and the system will automati-cally check whether students have conflicting class times.When scheduling classes in a new semester, the training officeor college can refer to previous scheduling information andcopy the scheduling information of certain courses as neededto reduce the maintenance workload.

3.2. Digital Campus Environment Living System. The smartcampus software system is the window of the school’s infor-matization construction, which can show the information ofeach interface for students and can allow users to easily findthe desired information or resource portal, etc, reduce codereuse rate, consider the need for future code expansion,and carry out the construction and maintenance of coderules, that is, calibrate data standard rules. The databaseserver adopts a minicomputer system and runs the informa-tion campus database in different partitions through physi-cal partition technology. All the platform systems of thesmart campus should be reflected in the school portal, andschool news and notices can be released in time to showthe development and progress of the campus. The construc-tion of the campus information portal is not only a windowfor the school to display to the outside world but also an

important platform for teachers, students, faculty members,and other personnel to carry out unified identity authentica-tion, based on which the entrance to other application sys-tems can be easily found, providing great convenience tousers. We believe that an important symbol of a digital cam-pus is the construction of a campus information portal [24].If the campus information portal is not well planned, it willbe difficult to carry out the whole digital campus construc-tion in depth. The training office or college can refer to thepast scheduling information and copy the scheduling infor-mation of certain courses as needed to reduce the mainte-nance workload. The information portal is a center ofvarious information collections, which can provide relevantinformation inquiry and release some information relatedto the column, which will be displayed on the school’s portalafter review. The campus portal is a large network platformintegrating news release, content management, video ondemand, image retrieval, full-text search, and other func-tions, as shown in Figure 3.

An intelligent access control system uses a card accesscontrol machine, license plate recognition, remote identifica-tion, and other access control equipment for linkage integra-tion. In addition to controlling the entry and exit of vehicles,it can further calculate and control the number of live-restricted parking spaces, strengthen the antitheft/preven-tion function, and make the vehicles pass through theentrances and exits more effectively identified and managed[25]. All-important departments of the college, trainingareas, and machine rooms are accessed using access cards,and the permissions of each faculty member and studentcan be managed in the background. On this basis, it can becombined with a personnel attendance system to realizeintelligent attendance and unified access to the college net-work for remote management. The digital campus is a sys-tem that takes the network and digital information as thebasis and makes the teaching resources more fully utilized

by students, teachers, and managers. Teachers, in addition tohaving the same operation rights as students, can also accessthe teaching videos and animations of relevant coursesthrough this system. Administrators can use this system toefficiently integrate school-related information and canrelease daily school arrangements to students and teachersthrough this platform, such as notification of school closuresand power outages, so that the information notified to stu-dents, teachers, and other administrators can be notifiedwithin the first time. The above are the functions that canbe provided by the smart card, but some additional func-tions will be added later to improve the interface of the sys-tem, to improve the quality of the system to achieve thepurpose of improving the core competitiveness.

It completes the functions of the electronic library cardand becomes the input medium of the library managementapplication system. The system replaces the campus cardwith the library card. Students need to verify their identitywhen entering the library, and they need to swipe their cardsat the card machine at the entrance of the library before thelibrary will open, and they also need to swipe their cards toregister their identity information when borrowing books.Through this system, the relevant information of the schoolcan be efficiently integrated, and the daily arrangements ofthe school can be released to students and teachers throughthis platform, such as the notice of rest and power outage, sothat the information notified by the school can be notified inthe first-time students, teachers, and other administrators.The system uses the student card instead of the key, whenstudents enter the dormitory need to brush the card, identityverification, only in the corresponding dormitory buildingstudent card can open the dormitory door, in the dormitorysuch as the population, male and female dormitory mainchannel, training building entrance to install access controlequipment, access control system is conducive to improvingthe security of the school, prevent irrelevant workers stepinto the campus, affect the normal campus environmentorder, effectively prevent internal theft, burglary, and cam-pus violations from occurring. The consumption systemmainly includes the meal charge system for teachers and stu-dents, the supermarket charge system, and the drinkingwater charge system. The main function of the consumptionsystem is to make the daily consumption of students andteachers inside the school safer and more transparent, forexample, eating in the school’s dining hall will send the dailyconsumption records to the APP, which can show the diningconsumption for a month and the average daily consump-tion, etc. In addition, other consumption of students insidethe school will also be recorded, such as drinking waterand supermarkets, in which no cash consumption and oldcard spending.

Teachers and students will be integrated with the com-prehensive application system to realize data sharing so thatthe comprehensive application system for teachers and stu-dents will become a whole and create a convenient, fast,and humanized campus electronic life for teachers and stu-dents. It is a comprehensive information platform forteachers and students to enroll, teach, train, live, seek jobs,learn skills, graduate, and resign. Nowadays, in the era of

rapid development of information technology, this is bothan opportunity and a challenge for the school managementsystem. The establishment of an integrated work systemplatform has more efficient work efficiency than traditionalcampus management and can also accurately serve faculty,staff, and students, to a greater extent, allow data to generatemore shared value and establish a data exchange mecha-nism. On the one hand, the background of this era providesa more excellent network environment for the informationsystem, and on the other hand, the information system facesmore dangers due to the rapidly developing network envi-ronment. While the business is expanding, the emergenceof education administration system not only provides userswith a convenient and quick way to manage various tediouseducation affairs but also liberates the education depart-ment, streamlining administration, reducing recurringexpenses, and using existing resources can bring greater ben-efits, as shown in Figure 4.

Nowadays, in the era of rapid development of informa-tion technology, this is both an opportunity and a challengefor the school management system. On the one hand, thebackground of this great era provides a more excellent net-work environment for the information system, and on theother hand, the rapidly developing network environmentmakes the information system face more dangers. Whilethe business is expanding, the emergence of the educationadministration system not only provides users with a conve-nient and quick way to manage various tedious educationaffairs but also liberates the education department, stream-lining administration, reducing recurring expenses, andusing existing resources can bring greater benefits. The edu-cational management system has been developed followingthe characteristics of universities. The key covers teachingmanagement, teacher management, curriculum manage-ment, examination management, and training management[26]. The rational arrangement of these divisions of labormakes staff members more focused on their jobs and greatlyimproves the efficiency of their work.

To realize the decentralized campus monitoring system,we must first ensure the stability and security of the databaseand secondly realize the perfect unification of the databaseand each technology, such as network monitoring [27] andauthority allocation, and unified management of all devicesand users. The system can greatly simplify and standardizethis process, realize information sharing and business collab-oration between the upper and lower departments, and con-nect with departmental budgeting, recruitment, accounting,and fund clearing systems. The establishment of an onlinepayment system mainly solves the problem of reimburse-ment of research funds. In colleges and universities, teachersconduct various kinds of research, in which the accountingand issuance of funds generated is a complex process. Thissystem can greatly make this process streamlined and stan-dardized; realize information sharing and business collabora-tion between upper- and lower-level departments; connectwith a departmental budget, procurement, accounting pro-cessing, and fund clearing systems; realize asset change appli-cation; approve financial accounting; and realize the whole lifecycle management of the whole assets.


4. Analysis of Results

4.1. All-in-One System Testing. Software testing, that is, theuse of test equipment to carry out performance and func-tional tests on the product according to the test strategyand procedures, and even the design of different test equip-ment according to the requirements, was designed to main-tain the system and the comprehensive evaluation of thevarious types of problems that arise in the test strategy. Afterthe test cases executed, the exceptions are followed up toensure that these developed products meet the detailed reg-ulations. When designing the above test cases, the status ofillegal user input and boundary conditions should be ana-lyzed. The user’s software should be tested to prevent anysurprises. Confirmation of the test results should be carriedout, and the errors of the test are often determined byanother person when carrying out the confirmation. Forthe more prominent problems, a meeting can be consideredto discuss and determine. With the help of the test results, itis possible to find out if the problem exists and the severityof the problem. The design goal of the test case for addingstudent status is to test whether the function of adding stu-dent status can be used to verify whether the user’s inputinformation is legal. When the data entered by the user isincorrect, the root cause of the error should be given andentered again. The goal of the Add Student Registration testcase is to test whether the Add Student Registration featureis available to verify that the user’s entry is legitimate. Whenthe data entered by the user is wrong, the root cause of theerror is given and entered again; after the user enters theaccurate test data, is it possible to add the school registrationinformation. During the system testing period, three roundsof testing were implemented, and the results of each roundwere counted after finishing the testing operation, and the

related fixes were implemented after each round of testing.The bug count record table for the three rounds of testingis detailed in Figure 5.

Performance testing intends to verify whether the per-formance of the application system can meet the relevantregulations of users and can learn the outstanding prob-lems such as system bottlenecks and performance in theapplication system and provide powerful help for softwareimprovement and overall optimization. In the teacher space,teacher users can complete three basic tasks: managing stu-dent information, managing course videos, and live teaching.In student information management, teachers can view theinformation of all students who choose the course they teach,as well as manage students’ grades after completing the course.In Manage Course Videos, teachers can view their existingcourse video information and add new course videos. Onceteachers upload their courses, they can see the courses theyhave added on the Watch Course page. Figure 6 shows theinterface for watching course videos, where teachers can seetheir course type, number, name, and view the entire list ofcourse videos. In addition, teachers can enter under the SearchCourse Videos tab to search for other teachers’ course videos,which can also be watched and studied after purchase.

Software testers are generally separated from systemdevelopers, i.e., software testers are specialized in softwaretesting. Black box testing is mainly functional testing. Itmainly tests the functions of the software. It is assumed thatthe tester does not understand the functional structure of thesystem and knows the program structure of the system; thetester mainly tests whether the various functions of the soft-ware system meet the requirements. White box testing gen-erally uses the test case approach, in which the systemfunctions of the software are visible to the tester and the soft-ware tester understands the functional structure of the

4.2. Performance Test Results. In addition to completing thebasic functions, the load capacity of the system must betested to make the user experience better. In this paper, weuse HBase, a nonrelational database with massive resourcestorage, to form a high-performance cloud storage environ-ment during the development of the system, and we conducta stress test on the database below. First, we import millionsof simulated data in the educational storage resource tableand then conduct four tests of sequential read, sequential

From Figure 7, using the HBase database as the cloudservice center of the system can complete the storage of mas-sive educational resources and meet the access requirementsof users. About the relevant requirements of digital campusconstruction, a unified information portal platform design,a unified identity demonstration platform design, and a uni-fied information resource planning quasiconstruction aregiven; the above design enables the campus to integrateand extend the existing system, which greatly reduces thecost and achieves the expected service effect. In the construc-tion of the digital campus teaching management system ofhigher education institutions, various information resourcesof the school are integrated in a scientific and standardizedway, and unified authority control, resource management,and user management are formed so that the school candevelop better with the reengineering of organization andbusiness process; system innovation andmanagement innova-tion are carried out through the construction of the project,and finally, information education, scientific management,and choice are completed in a more standardized way. Thebasic functions of the digital campus teaching managementsystem are realized, and on this basis, through the explorationof the construction of digital campus teaching managementsystem in higher education institutions, and employment-oriented digital campus structure is formed, combining thecharacteristics of higher education institutions, with compre-hensive and reasonable planning, highlighting the servicesfor teachers, students and employing departments, and takingstudents’ employment as the fundamental purpose.

Three functional modules, including cloud service cen-ter, teaching resource management, and remote classroom,demonstrated the implementation effect of the smart teach-ing system proposed in this article, completed the functional

test of the system and performed performance test on theload capacity of the database and the function of the serviceinterface. Finally, the advantages of the system proposed inthis paper are analyzed. In addition, the system services needto be tested; here, two services are selected for stress testing,resource management, and remote classroom; the specifictest method is to select the two types of interfaces providedby the service read and write, in a minute time, by changingthe number of clients and send requests, to obtain the aver-age of the number of outputs per minute for each service, inpages/min. Test results are shown in Figure 8.

By analyzing the data in Figure 8, the system can still runstably and meet the basic requirements of the design underthe high concurrency of the service. A brief overview of therequirements analysis and framework design to be completedin the specific implementation of the intelligent teaching sys-tem is given; then, the specific development environment ofthe system and the relevant details of the system service imple-mentation are introduced; then, the effect of the implementa-tion of the intelligent teaching system proposed in this paper isdemonstrated from three functional modules, such as cloudservice center, teaching resource management, and remoteclassroom, and the functional test of the system is completed,and the load capacity of the database. Finally, the advantagesof the system proposed in this paper are analyzed.

It introduces the requirements of the digital campus aca-demic affairs management system, analyzes the performanceand requirements of the university’s academic affairs networkmanagement system, and analyzes the detailed requirementsof each management module and usage function; introducesthe application of the digital campus academic affairs manage-ment system in the process of using, such as informationresource sharing, academic completion monitoring, andteaching assessment, and optimizes the design of each man-agement module; and carries out the interface implementation

and testing of various data and management rules in theprocess of using the academic affairs network managementsystem developed in this project. The design of the manage-ment modules is optimized, and the interface of the academicaffairs network management system developed in this projectis implemented and tested in the process of using various dataand management rules in the school. It is a web platform sys-tem focusing on the design of the academic affairs networkmanagement, using J2EE as the development platform and ahybrid C/S and B/S structure, and proposes an innovativeinformation-based academic affairs networkmanagement sys-tem. Through the digital campus academic affairs manage-ment system, the sharing of information resources andapplication operations are realized; based on the digital cam-pus academic affairs management system, course scheduling,learning achievement monitoring, and teachers’ teachingquality assessment are carried out; it has the significance ofpromoting and reforming the use and development of the uni-versity academic affairs network management system.

5. Conclusion

This paper completes the design of the university postgrad-uate management information system, which meets theactual situation and requirements of postgraduate manage-ment; realizes the functions of postgraduate academic regis-tration management, training program management, andtraining plan development; and provides convenience forpostgraduate training management. The system started trialoperation online, and the system database software wasdeployed on two physical servers using Oracle, and the

application server was deployed on two virtual machineson blade servers using WebSphere 6.1. The graduate studentmanagement information system adopts the concept of “bigplatform and small application” in the design of a digitalcampus system. The struts technology architecture basedon J2EE architecture is designed with high efficiency andreusability, which makes the system have good maintainabil-ity and portability. While managing the system, the onlydata format standard belonging to the graduate system wasestablished, which lays the foundation for the later digitalcampus integration construction, simplifies the steps ofsharing data, and improves the operational efficiency of thesystem. This study focuses on the technical solution designfor the needs of a single application system of the postgrad-uate management information system. The digital campusconstruction will have a large amount of personal informa-tion about the transmission, the vast majority of which canbe said to carry confidential information, and the orientationof information also requires communication and coordina-tion between school departments and authorization.
