1. INTRODUCTION

1.1 GENERAL INTRODUCTION

The financial services industry offers great opportunities both for the investors

and for the companies providing services to the investors. Many Web sites provides

financial services to retail and institutional investors. Speculations in the stock

markets are very popular in the United States, India and Europe, where the number of

retail investors (i.e. online traders) is increasing every year.

The project named Finance Portal(FP) provides a variety of financial data andinformation, acting as an information hub for clients who are individual investors

requiring timely financial news and data to make their investment decisions.

1.2 STATEMENT OF THE PROBLEM

The main aim of the project is to create a web portal for giving financial news,

stock market information and keep the portfolio of client. Nowadays for getting

adequate information about financial market one must have to visit different websites,

collect the different information and group them to get a summarized form.

Also the investor needs to spend time for recording shareholding details of

each days market move. Otherwise investor wont aware of current share holding

status. Graph movements are not available in bookkeeping, authenticated information

aren't get, reason behind movements aren't get and not easily get major world market

indexes.

5/53

Finance Portal

Feasibility analysis is a test of a system proposal, according to its workability, impact on the

organization, ability to meet the user needs and effective use of resources. Thus when a new

application is proposed, it normally goes through a feasibility study before it is approved for

development. The main objective of feasibility study is not to solve the problem but acquire a sense of

its scope. During the study, the problem definition is crystallized and aspects of the problem to be

included in the system are determined. Every project is feasible, given unlimited resources and infinite

time. It is both necessary and prudent to evaluate of the project at the earliest possible time. So a

detailed study was carried out to check the workability of the system. During the feasibility study of the

project some primary area of interest is considered very carefully. They are:

Economic Feasibility: -

An evaluation of development cost weighed against the ultimate income or

benefit derived from the developed system or product can be described as economic

feasibility analysis. The system definitely calls for more economic investment as no

existing system exists. But, the investment can be justified by the returns the system

makes.

Technical Feasibility: -

A study of function, performance and constraint that may affect the ability to

achieve an acceptable system can be referred to as technical feasibility. As the system

requires minimum expertise for its operation and maintenance it can be stated to be

technically feasible.

Operational Feasibility :-

Proposed projects are beneficial only if they can be turned into informationsystems that will meet the organizations operating requirements. This test of

feasibility asks if the system will work when it is developed and installed. The project

Finance portal system is aimed to be used as a general purpose software. One of the

main problems faced during the development of a new system is getting acceptance

from user. Being general purpose software there are no resistance from the user as this

software is extremely beneficial for users.

3. SYSTEM DESIGN

3.1 INTRODUCTION

Design of the system is essentially a blue print or a plan for a solution for the

system. The primary objective in this case is to design a system which delivers the

functionality required by both the employer and job seekers to get the information

relevant to each one of them. Detail design focuses on refinement to the architectural

representation that lead to detail algorithm data structure and representation ofsoftware. System design is a creative art of inventing and developing inputs,

databases, files, methods, and procedures for processing to get a meaningful output

that satisfy the organization objectives.

Software design is considered as the main part of software engineering process

and is applied regardless of the software process model that is used. The foremost

factor to be kept in mind is that design is the place where quality is fostered in

software development. The system design includes the database design, the

requirements specification for inputs, processing and outputs. In the design stage, the

programming language and the platform in which the new system will run are also

decided.

There are several tools and techniques used for designing. These tools and

technique are:

Flow chart

Data flow diagram(DFDs)

Data Dictionary

Structured English

Decision table

Decision tree

The proposed system uses DFDs for designing purpose because it is found to

be more suitable for this particular system design.

3.1.1 Requirements of Specification

Software Requirement Specification (SRS) is a complete description of the

behaviour of the system to be developed. Generally there are functional and non

functional requirements with a system. Non functional requirements are requirements

which impose constraints on the design or implementation.

The following are the requirements

The system should have high performance.

The Database of the system must be secure.

The system should be easy to maintain.

The system is developed using J2EE technology so that it requires server

which is compatible to deploy the project.

There should be separate area for financial news, stock market information

and portfolio.

There should be separate accounts for registered users protected by

username and password

For the users to interact with the system a web browser is needed.

3.1.2.1 DFD-Data Flow Diagram

Analysis model helps as to understand the relationship between different

components in the system. Analysis model shows the user clearly, how a system will

function. This is the first technical representation of a system. The analysis modelling

must achieve three primary objectives.

To establish a basis for creation of software design.

To describe what the user requires.

To define set of requirements that can be validated once the software is built.

A data flow diagram is a graphical technique that depicts information flow and

transforms that are applied as data move from input to output. The DFD is used to

represent increasing information flow and functional details. A level 0 DFD also

7


8/53

Finance Portal

called fundamental system model represents the entire software elements as a single

bible with input and output indicated by incoming and outgoing arrows respectively.

The DFD is one of the most important tools used by the system analyst. It can

be used for the visualization of data processing. DFD provides a graphical

representation of the flow of data through an information system. DFD illustrates how

data is processed by a system in terms of inputs and outputs. It is a picture of system

processing and flow without excessive concern for details.

The DFD showing the top level of the system is called Context Diagram. It

should be an overview including basic inputs, processes and outputs. Then it is

exploded in to more detailed lower level diagram that shows additional features of the

system.

The purpose of DFD is to provide a semantic bridge between users and system

developers. The diagrams are graphical, eliminating thousands of words, logical

representations, modelling what system does, hierarchical, showing system at any

level of details; and Jargon less, allowing user interaction and reviewing.

The goal of data flow diagramming is to have a commonly understood model

of a system. The diagram is the basis of structured system analysis. Data flow

diagrams are supported by other techniques of structured system analysis such as data

structured diagram, data dictionaries and procedure representing techniques such as

decision tables, trees and structured English.

The basic elements of DFD are

Rounded rectangle / circle : Used to represent functions.

Arrows : Used to represent data flow.

Rectangles : Used to represent external entities.

Option box : used to represent data store.

External Entity

3.2 OUTPUT DESIGN

Output design is a process that involves designing necessary outputs in the

forms of report that should be given to the users according to the requirements.

Output, generally refers to the results and information that are generated by the

system. One of the most important factors of the system is the output it produces,

Efficient; Intelligible output design should improve the system relationships with the

user. When an analyst design computer output they identify the specific output that is

needed to meet the information requirements. Select methods for presenting

information create documents, report of the format that contains information produced

by the system. Since the reports are directly referred by the management for taking

decision and to draw conclusion they must be designed with almost care and details in

the reports must be simple, descriptive and clear to the user. Depending on the nature

of output required they can be displayed.

The objective of the output design is to convey the information of all the past

activities, current status and emphasize important events. The output generally refers

to the results and information that is generated from the system. Output from the

computers is required primarily to communicate the result of processing to the users.

They are also used to provide a permanent copy of these results for later

consideration.The main objectives of the output specifications are

9


10/53

Finance Portal

To interpret and communicate the results of the computer part of a system to

users in a form which they can understand and meet their requirements.

To communicate the output design specification to programmers in a way thatis unambiguous comprehensive and capable of being translated in to a

programming language.

Choosing the output media is also the foremost important thing to be

considered while drawing the outputs. The user depending upon the following can

choose the output media.

The suitability of the device to the particular application.

The need for hard copy. The response time required.

The location of the users.

The software/hardware available.

The cost of the media.

Once the medium has been chosen, the output can be specified in detail

appropriate to the device to be used.

The proposed system is a web application project and all the output forms are

web interface and these are implemented using JSP . For storing login information,

news, Stock market details and user details Oracle 10g Database is used as backend.

There approximately 20 screenshots in this project.

3.3 INPUT DESIGN

The user interface design is very important for any application. The goal

designing input data is to make data entry as easy and it should be free from error as

possible. Input design is the link between the information system and the user. The

collection of input data is the most expensive part of system.

The term describes a final system and the processes by which it is developed.

It refers to the technical specification that will be applied in implementing the

candidate system. It also includes the construction of programs and program testing.

Input design is the process of converting user-oriented inputs to a computer based

10


11/53

Finance Portal

format. The data is fed into the system using simple interactive forms. The forms have

been supplied with message so that user can enter data without facing any difficulty.

Errors entered by data entry operators can be controlled by correct input

design. The general input forms also check for or even prevent data duplication as

well as even deletion of important data. The goal of designing input interface is to

make data entry as easy, logical and error free as possible, inputs are made using

dialogues and data validations are done at the time of data input.

The input design is made into user-friendly atmosphere where the user can

perform the daily routine work without any ones help. The user friendly environment

created by the input design helps the end user to use the software in a more flexible

way and even the wrong entries by the user is correctly pointed out to the user.

The goal of designing input data is make the automation easy and free from

errors as possible. For providing a good input design for the application, easy data

input and selection features are adopted.

The activities to be carried out as part of the overall input process are as follows.

Data Recording.

Data transcription.

Data conversion

Data verification.

Data control.

Data transmission.

Data validation.

Data correction.

In this project there are input forms for the registration of jobseekers as well as

employers because of their varying purpose of use. The login form is common for all

the three types of users in the system. Another form used for input of data is search

form. There are mainly two types of search one from the employer side for resume

search and the other from jobseeker side for job search so it should also produce

11


12/53

Finance Portal

different forms for the employer and jobseeker. There is another form which is used

to get the complaint details and the details of the user who has complaint. This is also

useful for the future enhancement of the system and also for producing management

output. Another form is sub user creating form for administrator to create sub users.

The forms use some of the controls like textbox, radio button, drop down list etc.

The users need to login to the system to avail the services. The employers and

the job seekers have to go through the registration process before login to the system.

When storing login details the role id to identify the type of the user is also stored.

This is done internally so that the users need not know this. The username and

password are stored in session at the time of login. These values are used for

providing services to the user further. Taking into account the type of users with this

system it can be analyzed that the input forms in this system should be gentle rather

than colourful. Because of this the input forms are designed using light colours and

white background so that it no longer looks cluttering with colour.

3.4 DATABASE DESIGN

Database design activity deals with the design of the physical database. A key

is tp determine how the access path are to be implemented. A physical path is derived

from a logical path. Pointers, chains or other mechanisms may implement it. Like

other software engineering activities, data design creates (data architecting) creates a

model of data, and/or information that is represented in at a higher level of

abstraction. This data model is then refined into progressively more implementation

specific representation that can be processed by the computer system. In many

software applications, the architecture of the data will have a profound influence on

the architecture of the system that must process it.

The structure of data has always been an important part of the design. At the

program component level, the design of data structure and the associated algorithm

required to manipulate them is essential to the creation of high quality applications. At

the application level, the transition of data model into database is pivotal to achieving

the business objectives of the system. At the business level, the collection ofinformation stored in separate database are recognized into a data ware house enables

12


13/53

Finance Portal

data mining or knowledge discovery that can have an impact on the success of thee

business itself. In every case, data design plays an important role.

The general theme behind a database is to handle information as an integrated

whole. A database is a collection of interrelated data stored with minimum

redundancy to serve user more efficiently and quickly. The general objective of

database is to make information access easy, quick, inexpensive, integrated, and

shared by different applications and users. Applications or users can access data

through the database management system (DBMS).

Design considerations

The system is analyzed to the requirements and possible tables and fields are

determined. Once we have drawn up the list of possible tables and fields, the next step

in the logical database is to identify primary key of the table.

Primary keys

The Primary Key (PK) of a relational table uniquely identifies each record in

the table. It can either be a normal attribute that is guaranteed to be unique or it can be

generated by the DBMS. Primary keys may consist of a single attribute or multiple

attributes in combination.

Foreign Keys

A foreign Key (FK) is a key comprised of a field or multiple fields that to the

primary key of another table.

Defining Relationship

A relationship is the term used to describe a connection between related tables.

Stated another way, it means having shared fields in different tables that allow records

to reference record in another tables. There are three possible type of relationship:

One-To-One Relationship

13


14/53

Finance Portal

A One-To-One Relationship indicates that each record in the table may relate

to only one in another table.

One-To-Many-Relationship

A One-To-Many Relationship indicates that each record in the table may

relate to multiple records in a second table.

Many To-Many Relationships

A Many-To-Many Relationship indicates that many records in one table can

relate to many records in another table.

Normalization

Ideally an applications database should start with a fully normalized data

representation. Normalization is simply a method to analyze elements of data and

their relationships. Normalization is a formal process of developing data structures in

a manner that eliminates redundancy and promotes integrity. Normalization is

achieved through a series of steps each of which correspond to a normal form (N F).

the normal forms are a sequence of rules that are applied to progressively a database.

The functions of normalization are

To structure the data, so that any pertinent relationship between the entities

can be represented.

To permit retrieval of data in response to query and reports requests.

To simplify the maintenance of data through updating, insertions, and

deletions.

To reduce the need to restructure or recognize data when new application

requirements arise.

4.3 SELECTION OF SOFTWARE

About Java

Java was introduced by Sun Microsystems in 1995 and instantly created a new

sense of the interactive possibilities of the web. Originally it was called Oak. It was

mainly developed for the development of software for consumer electronic devices.

Both of the major Web browsers include a Java virtual machine (JVM). Almost all

major operating system developers (IBM, Microsoft and others) have added Java

complier as part of their product offerings.

17


18/53

Finance Portal

It is a platform independent language. It is the first programming language that

is not tied to any particular hardware or operating systems. Programs developed in

Java can be executed anywhere on any system. The Internet helped propel Java to the

forefront of programming, and Java, in turn, has had a profound effect on the Internet.

Java is a true object-oriented language. It is a programming language

expressly designed for use in the distributed environment of the Internet. It was

designed to have the look and feel of the C++ language, but it is simpler to use than

C++ and enforces a completely object-oriented view of programming. Java can be

used to create complete application that may run on a single computer or bedistributed among servers and clients in a network. Java is generally regarded as the

most strategic language in which to develop applications for the Web.

It comes with an extensive set of classes, arranged in packages. The object

model in Java is simple and easy to extend. It can also be used to build small

application modules or applets for use as part of a Web page. Applets make it possible

for a Web page user to interact with the page. Java could be easily incorporated into

the Web system. Before Java, the WWW was limited to the display of still images and

texts. But the incorporation of Java into Web pages has made it capable of supporting

animation, graphics, games, and a wide range of special effects.

The programs you create are portable in a network. The output is Byte code.

Byte code is a highly optimized set of instructions designed to be executed by the

Java run-time system. It is a code understood by any processor. Translating a Java

program into byte code helps makes it much easier to run a program in a wide varietyof environments. Your program is complied into Java byte code that can be run

anywhere in a network on a server or client that has a java virtual machine.

The Java virtual machine interprets the byte codes into code that will run on

the real computer hardware. We then get a class file with Class extension. Platform-

specific versions of your programs are no longer needed.

About J2EE

The Software Development Kit (SDK) comes mainly in 3 forms:

Java2 Standard Edition (J2SE)

Java2 Mobile Edition (J2ME)

Java2 Enterprise Edition (J2EE)

J2EE is a very effective concept used to build large scale components. It is an

updated version of Java. The Java Community Programs (JCP) formed it.

Why J2EE?

It is used to simultaneously handle 1000s of users 24 hours a day, 7 days a week,

without any downtime.

About JSP (Java Server Pages)

Java Server Pages are a technology for developing web pages that include

dynamic content. The first Java Server Pages specification draft was released by Sun

in early 1998. The JSP specification defines JSP as a technology for building the

application for generating dynamic Web content such as HTML, DHTML and XML.

A JSP contains standard mark up language elements such as HTML tags. JSP allows

you to separate the mark up language code, such as HTML from the programming

language. Instead of embedding HTML in programming code, JSP lets you to embed

specialized code into HTML pages. JSP defines a number of standard elements useful

for any web application, such as accessing Java Beans component, passing control

between pages and sharing information between request, pages and users. The

combination of standard elements and custom elements allows for creation ofpowerful web applications.

DATABASE Connectivity

JDBC Process

Although each J2EE component is different, J2EE components use a similar

process for interacting with a DBMS. This process is divided into five routines. These

include:

Loading the JDBC driver

The JDBC driver must be loaded before the J2EE component can connect to

the DBMS. The Class.forName() method is used to load the JDBC driver. The

parameter used in this method is sun.jdbc.odbc.JdbcOdbcDriver.

Connecting to the DBMS

Once the driver is loaded, the J2EEcomponent must connect to the DBMS

using the DriverManager.getConnection() method. The Java.sql.DriverManager class

in java.sql hierarchy is responsible for managing driver information. This method

returns a Connection interface that is used throughout the process to reference the

database.

Create and Execute SQL Statement

The next step after the connection is established is to send SQL query to

DBMS for processing. The connect.createStatement () method is used to create a

Statement object. The Statement object is then used to execute a query and return a

Result Set object that contains the response from the database. Typically query is

assigned to a String object, which is passed to the Statement objects execute Query ()

method. Once the Result Set is received from the Database, the close () method is

called to terminate the statement.

20


21/53

Finance Portal

Process Data Returned by the DBMS

The java.sql.ResultSet object is assigned the results received from the DBMSafter the query is processed. This object consists of methods used to interact with data

that is returned by the DBMS to the J2EE component.

Terminate the Connection to the DBMS

The connection to the DBMS is terminated by using the close() method of the

Connection object once the J2Eecomponent is finished accessing the DBMS.

Although the database connection automatically closes the Result Set object, it isbetter to close the Result Set explicitly before closing the connection

5. SYSTEM TESTING

System testing is a critical element of software quality assurance andrepresents the ultimate review of specification, design and coding. Testing is the

process of exercising or evaluating a system by manual or automatic means to verify

that it satisfies the specified requirements or to identify difference between actual and

expected results. Testing enhances the integrity of a system by identifying deviations

in design and development of the expected product. It should focus more on the error

prone areas of application. Testing is an important part of the software development

process, to detect bugs, improve software design and to reduce usability problems.

5.1 Purpose

A good test case is one that has a high probability of finding an as yet

undiscovered error. They are all about making sure that the product fulfils the

requirement of the system. Then all about making sure that the product fulfils the

requirement of the system. Then the test procedures are designed for these test cases

and finally test scripts are created to implement the procedures. Two types of test case

designs are white box testing and black box testing. White box testing also called

glass-box testing focus on the program control structure. Black box testing method

focuses on the functional requirements of the software.

5.2 Quality

Quality software is reasonably bug-free, delivered on time and within budget,

meets requirements and/or expectations, and is maintainable. However, quality is

obviously subjective term. It will depend on who the customer is and their overall

influence in the scheme of things. A wide-angle view of the customers of a software

development project might include end-users, customer acceptance testers, customer

contract officers, customer management, the development organizations management

/accounts/testers/sales people, future software maintenance engineers, stockholders,

magazine columnists, etc. Each type of customer will have their slant on quality- the

22


23/53

Finance Portal

accounting department might define quality in terms of profits while an end-user

might define quality as user-friendly and bug-free.

Design and development planning should culminate in a plan that identifiers

necessary tasks, procedures for anomaly reporting and resolution, necessary

resources, and management review requirements, including formal design reviews. A

software life cycle model and associated and activities should be identified, as well as

those tasks necessary for each software life cycle activity.

The software quality plan should include:

The specific tasks for each life cycle activity;

Enumeration of important quality factors (e.g.: reliability,

maintainability, and usability);

Method and procedure for each task;

Task acceptance criteria;

Criteria for defining and documenting outputs in terms that will allow

evaluation of their conformance to input requirements;

Input for each task;

Output from each task;

Role, resources, and responsibility for each task;

Documentation of user needs;

5.3 Testing Strategies

A strategy for software testing integrates software test case design methods in

to a well planned series of steps that results in the successful construction of the

software. The strategy provides a road map that describes the step to be conducted aspart of testing, when these steps are planned and undertaken, and how much effort,

time and resources will be required. Therefore any testing strategy must incorporate

test planning, test case, design, test execution and resultant data collection and

evaluation. A software testing strategy should be flexible enough to promote

customized testing approach. At the same time, it must be rigid enough to promote

reasonable planning and management tracking as the project processes. The project

23


24/53

Finance Portal

manager, software engineer and testing specialists develop a strategy for software

testing. The general characteristics of software testing strategy are:

1 Testing begins at the component level and works outward toward the

integration of the entire computer system.

2 Different testing techniques are appropriate at different point in time.

A strategy for software testing must accommodate low-level testis that are

necessary to verify a small source code segment has been correctly implemented as

well as high level testing that validate major system function against customer

requirements.

5.4 Dimensions of Testing

1. Unit Testing.

2. Integration Testing.

3. User acceptance Testing.

4. Data validation Testing.

5. Final Testing.

5.4.1 Unit Testing

Unit test comprises of a set test performed by an individual programmer prior

to the integration of the unit into large system. Program unit is usually small enough

that the programmers who developed and can it in great detail and certainly in greater

than will possible when the unit is integrated into evolving software project. Module

unit testing should be an exhaustive as possible to ensure that each representation is

handled by each module has been test.

55555 Integration Testing

Integration testing is a system technique for constructing the program structure

while at the same time conducting test to uncover errors associated with interfacing.

The objective is to take unit testing modules and build a program structure that has

been dictated by design. Bottom-up integration is the traditional strategy used to

integrate the components of a software system into functioning whole. Bottom-up

integration consists of a unit test followed by testing of the entire system. Subsystem

consists of several modules that communicated with other defined interface. The

errors were isolated and corrected to produce a fully functional system. Top-down

integration method is an incremental approach to the construction of the program

structure.

5.4.2 Data Validation Testing

Data validation is the process of testing the accuracy of data; a set of rule you

can apply to a control to specify the type and range of data that can enter. It can be

used to display error alert when users enter incorrect values into a form.

5.4.3 Final Testing

Final testing is a kind of testing and it comes at the final stage. It should be

performed after inspection. It can defects whose consequences obvious but which are

buried in complex code, and thus will be hard to detect while inspection.

Project testing details

In the project first step of testing is carried out through unit testing. In unit testing

each form are verified separately. i.e. Modules of the software are tested separately. It

is very easy to find errors and debug the software. After unit testing the integration

testing is carried out. Integrated testing is used to find the overall software

performance.

In project implementation phase, source code contains both global and formal

variables. It contains predefined functions as well as the user defined functions. The

results of the new system are compared with old systems and if the result is wrong

then the error is debugged again.

Procedures and functions in the new system are very simple as that any one can

understand and correspondingly act by the system with no difficulty.

6. SYSTEM IMPEMENTATION

The final and important phase in the system in the life cycle is the

implementation of the new system. The term implementation has different meanings

ranging from the conversion of a basic application to a complete replacement of a

computer system. The procedure however, is virtually the same. Implementation

includes all those activities that take place to convert from old system to new. The

new system may be totally new replacing an existing system manual or automated or

it may be major modification to an existing system.

Implementation simply means converting a new system into operation. An

important aspect of the system analysts job is to make sure that the new design is

implemented to establish standards. Implementation means the process of converting

a new revised system in an operational one.

The three types of implementation are

Implementation of new computer system to replace an existing one.

Implementation of modified application to replace an existing one.

Implementation of a computer system to replace manual system.

The method of implementation and time scale to be adopted is found out

initially. Next the system is tested properly and at the same time users are trained in

the new procedure .Proper implementation is essential to provide a reliable system to

meet organization requirements. Successful implementation may not guarantee

improvement in the organization using the new system, but it will prevent improper

installation. The implementation involves the following things.

Careful Planning

Investigation of the system considerations.

Design the method to achieve the changeover.

Evaluation of change over method.

Implementation of a new system requires the operating staff installing the

software and creating computer files. There are many ways in which this can be

achieved. The most common method is following.

26

Direct change over.

Parallel Running.

Pilot Running Change Over.

Conversion

The objective of conversion is to put the tested system into operation while

holding costs, risks and personal problem to minimum.

It involves three major steps

Creating computer compatible files.

Training the operation staff.

Installing hardware/Software.

Procedures and documents are unique to the conversion phase.

Project implementation Details

The proposed system Finance portal is a not entirely a new system in this

category. This system is developed to eliminate the disadvantages of existing system.

All the functionalities provided at the interface are developed using JSP using the

editor Dream Weaver and the web server used for the deployment purpose is Tomcat.

The database used is Oracle 10g for data storing.

. The system is developed using platform independent language so that it will

work with most of the platforms. Since it is a web based system the users of the

system will reside remotely. Most of the browsers available today are compatible with

the system so that the users can users any browser that is available with them.

7. CONCLUSION

The project Finance Portal was completed successfully. This serves as a

single point for giving updated financial information. All inputs given are validated

properly, which makes the output more accurate. The system is more flexible and can

be modified easily whenever needed.

This system has been developed after going through all the phases in the

development of the software. It has been developed to be user-friendly. The interfaces

are designed and coded in such a way to minimize user input there by restricting the

time and effort taken during the data entry process. This software is developed in such

a way that future enhancements can be incorporated with a little change in the coding.

The system is now designed so that the every novice user can use it in a very

friendly manner. Comparing with other websites, this software and website will

provide more friendliness to users. Since the system is developed using J2EE, it is

platform independent and it can be run on any type of platform currently available.

All the types of the phases such as system study, analysis, design etc are done and the

several testing steps are also completed. The users are satisfied in all these aspects and

so the system is very necessary. However we can add more details and make the

system friendlier in the future.

Also measure can be taken to enhance security features. All suggestions in the

system proposal have been successfully completed and final threshold of the

application has been crossed.

8. FUTURE ENHANCEMENTS

Changes in software engineering technology are indeed rapid. By the time adecision is made to adopt a new method, conduct the training necessary to understand

its application and introduce the technology into the software development culture,

something new and bettor has come along, and the process begins.

Computer software is one of the few key technologies that will have a

significant impact on nearly every aspect of modern society. It is a medium for

automating business, industry and government. It is also a medium for transferring

new technology, a method for capturing valuable expertise for use by others and a

window into a corporations knowledge.

The purpose of future enhancement is to make updating in the developed

software as the needs arise and the new technology comes. The future enhancement is

subjected to the user needs and the technological growth. The system has been design

and developed flexibly according to the current requirement of the user. As the

information requirements may still increase in the near future. Further such

development can be attempted.

The following enhancement will be done in future.

1. In future the market module can be enhanced by technical analysis such as

candle stick chart.

2. More services to the registered user by adding investors forum, mutual

fund prices.

3. Message alerts through SMS by incorporating mobile phone services.

4. Facility to view live multimedia report from reporter.

5. Facility to read company balance sheet, auditors report etc
