Organization overview &

Introduction:

This system “Inventory system” has been developed by Ms. AMRITA SINGH as an academic project for the Computer Science Department of S.K. College of Science & Commerce as a part of the T.Y. BSc Computer Science Course.

This system was created with a lot of anticipation towards mastering the basics of system creation .It was designed in such a way so as to help us make use of basic technologies like Visual Studio and MS SQL .It has used the concepts of maintaining a uniform system structure and during the process of creating this system an honest effort has been made towards creating a professional system in the future.

8


Description of the System:

During the past several decade’s personnel function has been transformed from a relatively obscure record keeping staff to central and top level management function. There are many factors that have influenced this transformation like technological advances, professionalism, and general recognition of human beings as most important resources.

A computer based management system is designed to handle the entire

primary Information required to calculate monthly statements. Separate

database is maintained to handle all the details required for the correct

statement calculation and generation.

This project intends to introduce more user friendliness in the various

activities such as record updating, maintenance, and searching.

The searching of record has been made quite simple as all the details of

the Book can be obtained by simply keying in the identification of those

Books.

Similarly, record maintenance and updating can also be accomplished by

using the identification of the Book with all the details being

automatically generated. These details are also being promptly

automatically updated in the Master files thus keeping the record

absolutely up-to-date.

9


The entire information has maintained in the database or Files and

whoever wants to retrieve can’t retrieve, only authorization user can

retrieve the necessary information which can be easily is accessible from

the file.

Limitations of the Present System:

The present system has several shortcomings that are as follows:-

In Present system each and every record is maintains in registers, so

there will be lot of redundancy in maintain book records.

Also there is no security due to all records are maintain in register.

Modification of one record causes to other records related to that record,

so work becomes very critical, so some time data loss will be ocular.

Storage of information is costly.

Require knowledge about this system.

More time required for reading & adding records in register

Searching any old record of any job done or damaged required more

time due to critical system of register.

10


Proposed System:

This system computerized all the requirements of the owner. It will give the owner the feature of maintaining all the profiles of its customer, Suppliers, the Product in which the owner deals in, the companies of whose product the owner sells. It gives the user the functionality of searching stock without manually checking it as stock entries are updated throughout the sales and purchase transaction. It also keeps track of the enquiries made in the owner by various people.

OBJECTIVES

1) Data management.

2) Data retrieval at will.

3) Data modification.

4) Save time thereby increasing performance.

5) Reducing work process time.

6) Provide various report facility.

7) Cost effective and less manpower required.

11


Advantages of The Proposed System:

This system uses MS SQL as data base which is strong and secure

database for proposed system.

The proposed system empowers the user with a new computer based

system by reducing the efforts of data maintenance.

The proposed developed according to the user specification hence it is a

user-centered system.

This system provides a facility to generate a bill as soon as the customer

purchases a product.

If the customer has not paid the full payment then there is a facility to

check the balance amount that has to be paid by the customer.

12


Limitation of the Proposed System :

The system prepared is competent but we cannot say that it is a perfect

system. This system like any other system has some flaws &

shortcomings in it. They are as follows:

This system is semi-functional. This means that the system covers the

manipulation related to the record only.

Only one person can use the system.

There would be high rate & better quality of performance.

System requirementsSystem requirements

Hardware and software requirements:

The least hardware requirements are:

1) Minimum 2 GB HDD space2) Pentium or Celeron based processor

13


3) 128 MB RAM

The least software requirements are:

1) Operating system: - Windows XP, Windows7.

2) Front-end Tool: - Visual studio 2008.

3) Back-end Tool: - MS SQL Server 2005.

4) Report Generation: - Crystal Report Basic.

FEASIBILITY STUDY

Every project would be feasible, if provided with

unlimited resources and unlimited time. But unfortunately, the

development of computer-based system of book is more likely plagued

by a security of resources and difficult time constraint. It is both

necessary and prudent to evaluate the feasibility of the project at the

earliest possible time. During software engineering we concentrate our

attention on four primary area of interest. The techniques used in

conducting an initial investigation and feasibility study are very similar

but the objectives are not so.

The major objectives of feasibility study are to further define the

problem and to determine the best way to solve it. The typical primary

objectives are:

14


• A centralized database will be developed.

• Runtime operating decision-making will be eliminated.

• Unnecessary control procedure will be automated.

• The minimum of paper work should be produced.

• The output produced by the system should be in a usable format

System Analysis

STAKE HOLDERS

A corporate stake holder is a party that can affect or be affected by

the actions of the business as a whole.

TYPES OF STAKE HOLDERS:

Internal stake holder

17


Internal stake holders-Market (or primary)Stake holders are those that

are engaged in economic transactions with the business.

External stake holders-

Non market(or secondary) stake holders are those who although they do

not engaged in direct economic exchange with the business are

affected by or can affect its actions.

Owner

The owner of the admission system needs to keep a check on

everything which is visiting admission system about each and every

registration and viewing and making changes i.e. update, delete etc. this is

one of the important issue to be handled . Book should be updated

regularly as if the new book comes in to avoid any mistake.

FACT FINDING TECHNIQUES:

18


The system referred is the “Inventory system” that deals with the bills of the customer & supplier. The following are the fact-finding techniques, which were followed:

1) Going through all the existing documentation, files, registers:

I went through all the files and registers in which the supplier’s details were kept. I also referred the handmade bills and receipts. From this I traced out the history, which was required for the existing system to be implemented.

2) Research and site visit:

I visited the shop several times, which was very important for gathering the details about the items stored in the shop and the how the bill is generated.

3) Observation:

By visiting the shop I observed how the manual process is been taking place. Through observation I was able to see what exactly is to be done.

4) Questionnaires:

Questionnaires are the special purpose documents that allowed me to collect information and opinions from respondents. Through questionnaires it was possible to know the requirements of the respondent.

5) Interviews:

Through interviews it was possible for me to collect information from the respondent face-to-face

Event Table

Class Diagram

The class diagram is used to refine the use case diagram and define a detailed

design of the system. The class diagram classifies the actors defined in the use case

diagram into a set of interrelated classes. The relationship or association between the

classes can be either an "is-a" or "has-a" relationship. Each class in the class diagram may

be capable of providing certain functionalities.

28


Sequence Diagram

A sequence diagram represents the interaction between different objects in the

system. The important aspect of a sequence diagram is that it is time-ordered. This means

that the exact sequence of the interactions between the objects is represented step by step.

Different objects in the sequence diagram interact with each other by passing "messages".

29


COLLABORATION DIAGRAMA collaboration diagram, also called a communication diagram or interaction

diagram, is an illustration of the relationships and interactions among software objects in the Unified Modeling Language.

Component Diagram

The component diagram represents the high-level parts that make up the system.

This diagram depicts, at a high level, what components form part of the system and how

they are interrelated. A component diagram depicts the components culled after the

system has undergone the development or construction phase.

33


Package Diagram A package diagram in the Unified Modeling Language depicts

the dependencies between the packages that make up a model. Package diagrams can use packages containing use cases to illustrate the functionality of a software system

Validation

42


There are many approaches to software testing. Reviews, walkthroughs, or inspections are considered as static testing, whereas actually executing programmed code with a given set of test cases is referred to as dynamic testing. Static testing can be (and unfortunately in practice often is) omitted. Dynamic testing takes place when the program itself is used for the first time (which is generally considered the beginning of the testing stage). Dynamic testing may begin before the program is 100% complete in order to test particular sections of code (modules or discrete functions). Typical techniques for this are either using stubs/drivers or execution from a debugger environment. For example, spreadsheet programs are, by their very nature, tested to a large extent interactively ("on the fly"), with results displayed immediately after each calculation or text manipulation.

White box testing is when the tester has access to the internal data structures and algorithms including the code that implement these.

Types of white box testing

The following types of white box testing exist:

API testing (application programming interface) - testing of the application using public and private APIs

Code coverage - creating tests to satisfy some criteria of code coverage (e.g., the test designer can create tests to cause all statements in the program to be executed at least once)

Fault injection methods - improving the coverage of a test by introducing faults to test code paths

Test coverage

White box testing methods can also be used to evaluate the completeness of a test suite that was created with black box testing methods. This allows the software team to examine parts

43


of a system that are rarely tested and ensures that the most important function points have been tested.

Two common forms of code coverage are:

Function coverage, which reports on functions executed Statement coverage, which reports on the number of lines executed to complete the

testThey both return code coverage metric, measured as a percentage.

Coding for validation

For Only Alphabets

If Char.IsLetter(e.KeyChar) Or Asc(e.KeyChar) = 127 Or Asc(e.KeyChar) = 8 Or Asc(e.KeyChar) = 11 Or Asc(e.KeyChar) = 13 Or Asc(e.KeyChar) = 32 Then e.Handled = False Else e.Handled = True End If

For Only Numbers

Private Function validatFields() As Boolean If Not IsNumeric(TextBox4.Text.Trim) Then MsgBox("Price must be a number") Return False End If Return True End Function

46


Test Case

The forms were tested for their functionality and error messages are displayed wherever the input does not meet the required requirements

Login form giving error message.

If any invalid user want to take entry into the system then this form restrict him from entering into the system. By entering invalid username or password it gives an error message

Add Book Form gives an error message.

Add Book form gives an error message if valid data entry is not done. For example, Price

should be numeric.

Update Book Form gives error message

Update Book form gives an error message if valid data entry is not done. For example, if no

book is selected then it gives an error message ‘Please select Book’.
