Synopsis - Mini Project

Green Bank - Online Banking Solution

Created by: Ankit Mishra

Course: MCA- Vth SemesterRoll No. 0671704406

Introduction

The project is intended to provide online banking facilities such as checking accounts, paying mobile bills, getting pay-in slips and making transfers over World Wide Web.

Customer is supposed to provide login id and password to access his bank account online.

With proper authorization the customer will be allowed to perform various bankingactivities. In addition to conventional banking services the customer is also facilitated

with service like recharging mobile accounts for Airtel customers

There are two major ends in this project the customer end and the administrator end.

• Customer end is the end where customers make requests to view their accountinformation update information and do transactions or pay certain bills.

• Administrator end is responsible for validating the user i.e. not allowing any

unauthorized person to access the account. In event of a customer forgetting theLogin password, provision has been made to provide password through a secure passage. Administrator is responsible for adding customers without affecting

existing customers.

Objective and Scope of the project

The main purpose of Online Banking Solution is to provide customers with an ability tomake transactions online over a very user friendly interface.

Facilities provided

• View Account: Customer is authorized to check his account.

• Transfer Money: Customer can transfer money online over a secure passage toanother account.

• Credit Card Facility: Customer can login using the credit card number. Acustomer can also apply for a credit card.

• Application Forms: Different forms such as new cheque book request, change ofaddress etc can be downloaded.

• Customer Help: A document enabling customers to understand Online Banking.

• Bill Payment: Bills pertaining electricity, mobile can be paid online.

• Mobile Recharge: In collaboration with Airtel, users can get their accountrecharged.

• Generate Account Statements

•

Architecture of Online Banking (Green Bank)

The Online Banking Application is based on 3-tiered model. The Enterprise

architecture forOnline Banking Green Bank).

Figure1: Architecture of Online Banking (Green Bank)

The 3-tiered architecture shown above has the following major components:

• Client: There will be two clients for the application. One will be a web-baseduser-friendly client called bank customers. The other will be for administration

purposes.

• Application Server: It takes care of the server script, takes care of JDBC-ODBCdriver, and checks for the ODBC connectivity for mapping to the database in

order to fulfill client and administrator’s request.

• Database: Database Servers will stores customer’s and bank data.

Software and Hardware Requirements

• Hardware requirements: P4 (2.4 GHz), 512 mb DDR ram

•

Operating System: Windows Xp(Professional) SP2• Software Requirements: Eclipse IDE, Apache tomcat 6.0.18, JavaScript, HTML,

JSP and Servlets, Oracle 8.1.7

Limitations

• The project can be best viewed on Firefox. • It provides banking facilities to personal banking. • Enterprise Java Beans have not been implemented. • SSL is not implemented. • Loan facilities, credit card login is not being provided.

ConclusionThis project shows, how Online applications like online Banking, can easily be developedusing Enterprises Java Technologies and its distributed architectures \[Page-Centric,

Page-View, and Model 1]. A more efficient approach would be to utilize Model ViewController 2 architecture, which makes application reusable, robust, and more object-

oriented the approach followed in this project.

Proposed System

Those that do are sometimes referred to as "brick-to-click" banks, both to

distinguish them from brick-and-mortar banks that have yet to offer online banking, as well as from online or "virtual" banks that have no physical branches

or tellers whatsoever.

The challenge for the banking industry has been to design this new servicechannel in such a way that its customers will readily learn to use and trust it. After

all, banks have spent generations earning our trust; they aren't about to risk that ona Web site that is frustrating, confusing or less than secure.

The proposed system will show the Online using Servlets and JSP and Oracle8i as

the backend. This project makes use of flash navigation menu bars which makes iteasier to navigate through the site and the project is build around MVC

architecture which makes it more robust system.The vision is simple and powerful: customers will be able to perform banking functionalities in an easy

manner .

Definition of Problem

The purpose of this project is to develop an on-line banking system that provides

customers with the facility to check their accounts and do transactions on-line.The system will provide all the banks facilities to its customers when their

authentications [user id and password] matches, including viewing accountinformation, performing fund transfers, giving the customer an option of changing

address, password retrieval, performing transactions, viewing transactions andlocate bank branches. The system allows and should allow customers to view

their personnel accounts and to pay bills online from their account.

The system should assign a unique transaction number to every transaction that auser makes.. The Administrator will administer both normal bank account. The

administrator have the ability to perform various operations like creating a normal

bank account for the customer and performing functions like transfers,withdrawals and deposits when the customers want teller transactions. Theadministrator also has the privilege to close the customer’s account on the request

of the bank customer. The customer should be able to access his/her accountfrom anywhere just by inputting the correct user-id and password.

Advantages of online banking

• Convenience: Unlike your corner bank, online banking sites never close;they're available 24 hours a day, seven days a week, and they're only a mouse

click away.

• Ubiquity: If you're out of state or even out of the country when a money problem arises, you can log on instantly to your online bank and take care of business, 24/7.

• Transaction speed: Online bank sites generally execute and confirmtransactions at or quicker than ATM processing speeds.

• Efficiency: You can access and manage all of your bank accounts, includingIRAs, CDs, even securities, from one secure site.

• Effectiveness: Many online banking sites now offer sophisticated tools,including account aggregation, stock quotes, rate alerts and portfolio managing programs to help you manage all of your assets more effectively. Most are also

compatible with money managing programs such as Quicken and MicrosoftMoney.

Disadvantages of online banking

•

Start-up may take time: In order to register for your bank's online program, youwill probably have to provide ID and sign a form at a bank branch. If you andyour spouse wish to view and manage your assets together online, one of you

may have to sign a durable power of attorney before the bank will display allof your holdings together.

• Learning curve: Banking sites can be difficult to navigate at first. Plan to investsome time and/or read the tutorials in order to become comfortable in your

virtual lobby.

•

Bank site changes: Even the largest banks periodically upgrade their online programs, adding new features in unfamiliar places. In some cases, you mayhave to re-enter account information.

• The trust thing: For many people, the biggest hurdle to online banking islearning to trust it. Did my transaction go through? Did I push the transfer button once or twice? Best bet: always print the transaction receipt and keep it

with your bank records until it shows up on your personal site and/or your bank statement.

Theoretical Background

Similar banking applications are available in the market. A considerable amount

of research has been done in past few months on this project. Many banks hadmigrated from paper based banking system to electronic online banking. Each

bank had its own, user friendly interface, which helps its customers to interactwith their account at their ease. A wide variety of Online Banking applications are

available in the market which in turn help the bank to function smoothly. All banks which are using online banking application uses the same basic principle.

Axis Bank

has excellent features, which allows customers to check their accounts and view

their statements. The best thing about this bank’s system allows us to schedule

payments and do online transactions. The security feature is the best; it gains thetrust of the customer and allows them to do their transitions in an efficient andsecure manner. However, the interface is very complicated for novice users. The

interface for credit card customer is confusing

Canara Bank

One of the finest bank of India , who perform their transactions online. Thesecurity issues are wonderful, and it allows the customer to view their

transactions, pay bills online, ATM/branch locator and provide

Project Scope

The Online banking Application project will be divided into 2 modules namely:

1. Bank Account2. Bank Account Administrator

Module 1

In this module the customer is allowed to logon to the website and can access

his/her account by getting user name and password which will be verified with theserver and the database. Once he/she gets verified then they are allowed to view

their personal account and perform operations such as change of address, paying bills online, viewing transactions and transferring money into other accounts.

Once the customer finishes the task the update information instantly gets stored

into the database. The customer is then allowed to sign out from his/her account.

Module 2

In this module the administrator is allowed to log on to the website and can accesshis/her administrative account by using the user name and password which will

then be verified with the database. Once he/she gets verified the administrativeinterface will be displayed, where the administrator can perform operations for

both new customers and existing customers. Administrator will help a newcustomer in opening their account by taking complete information from them.

Administrator provides services like withdrawal, deposit, transfer and deletingcustomer during the time of closing the account. In this module administrator

provides great customer service to the customers who want to do phone bankingor teller banking. The interface for administrator will be both very user friendly

and efficient. The data gets stored in the database instantly when the administratorhits the submit button.

Requirements Analysis

The requirements can be defined as “A complete understanding of the software

development effort. No matter how well designed or well coded, a poorlyanalyzed and specified program will disappoint the user and bring grief to the

developer.”

System requirements should set out what the system should do rather than howthis is done. A requirement may be a functional requirement, that is, it describesa system service or function. Alternatively, it may be a non-functionalrequirement. A non-functional requirement is a constraint placed on the system(for instance, the required response time) or on the development process (such as

the use of a specific language standard).

The Design process involves developing several models of the system at different

levels of abstraction. As a design is decomposed, errors and omissions in earlierstages are discovered. Design is a creative process. Although methods and

guidelines are helpful, judgment and flair are still required to design a softwaresystem.

Requirements may be either:

• Functional, describing the facilities of the system

• Non-functional, describing constraints which may impact later development phases

Feasibility Study

Feasibility is the determination of whether or not a project is worth doing. The process followed in making this determination is known as feasibility. It is very

necessary to evaluate the feasibility of a project. In the development of the present project, no such limitations were imposed that were not feasible.

All the projects are feasible given unlimited resources and infinite time.

Unfortunately the development of a computer-based system is more likely to be plagued by a scarcity of resources and difficult delivery date. Therefore it is both

necessary and prudent to evaluate the feasibility of a project. Hence this is themost important aspect in analysis part of any system. The feasibility study enables

us to know whether it is viable to go for computerization or not.

This is the most important aspect in the analysis part of the system. Designing phase is generally dependent upon the feasibility study. The feasibility study

enables us to determine whether it is feasible to go for computerization. Sokeeping this aspect in view the new computerized system has also undergone

many checks and then only it was decided to develop the system.

There are different modes of feasibility study.

• Technical FeasibilityThe technical feasibility is concerned withspecifying the equipments and software that will successfully satisfy theuser requirements. A system is technically feasible if it can be designed

and implemented with the limitations of available resources.The technical requirement i.e. the hardware and software required by the

new system is of low cost and needing very less maintenance cost. Thereis no need to buy anything extra for the system. The projected resources

are enough for the system. So the development of the new system istechnically feasible.

The proposed system is technically feasible as the resources that are

needed for the proposed system are available.

• Economic Feasibility

Economic feasibility analysis is most frequently used technique for

evaluating the effectiveness of the proposed system. It is also known asCost/Benefit Analysis. The proposed computerized system is

economically feasible, if the benefit in the long run compensates the costincurred in the designing and implementation of the system.


20/75

20 | P a g e

The cost factor of the system involves the Manpower cost, Hardware cost, and the

Software cost.

Manpower Cost: There is no need to employ any extra person to use this systemas its very user friendly and very easy to learn too.

Hardware Cost: The hardware cost is very less. So this system is economicallyregarding hardware cost.

Software Cost: The software needed for the development of the project is nil aswe are using Free and Open Source Software (FOSS) like Java.

The development of the proposed system does not result in too much extra

expenditure. The existing hardware and software will fulfill the requirement of the

proposed system. Thus, the proposed system is economically feasible.

§ Social Feasibility

Social feasibility is a determination of whether a proposed system will beacceptable to the people or not. This determination typically examines the

probability of the project being accepted by the group directly affected by the proposed change in system.

The proposed system helps to reduce the time of the user. So, the proposed system

is accepted by the user. Thus, the proposed system is socially feasible.

§ Legal Feasibility

Legal feasibility is a determination of whether the proposed system infringes on

any known Acts or pending legislations. We are using Free and Open SourceSoftware (FOSS) so the proposed system does not infringe on any legal Acts.

Thus, it is legally feasible.

§ Time Feasibility

Time feasibility determines whether the proposed project can be implemented

fully within the stipulated time frame.

The proposed system was allotted two months time for being implemented. Thetime allotted for the proposed system is quite sufficient. Thus, the proposed

system is time feasible.

Thus, the proposed system passes all the feasibility tests.

Comparison between J SP and other technologies

J SP vs. Active Server Pages(ASP)

ASP is a similar technology from Microsoft. The advantages of JSP are Saturday,

March 13 2004 two fold. First, the dynamic parts written in java , not VisualBasic or other MS-specific language, so its more powerful and easier to use.

Second, it is portable to other Operating systems and non-Microsoft Web servers.

J SP vs. J avaScript

Client-side scripting with JavaScript is certainly handy and useful, but it does

present several problems, including the following: You must count on thecustomer's browser to have scripting enabled, which, of course, you can t.

• Different customers may use different browsers. And coding client-sidescripts that work on different browsers can be a headache.

• Scripting languages used on the client side cannot match the strength andversatility of Java.

• Client-side scripting languages have very limited access to server-sideresources, such as databases. JavaServer pages have access to all server-

side resources within the well-defined architecture of J2EE.

• You have the usual problems of maintaining software on the client that

caused

Advantages of using JSP over competing technologies are as follows:

o JSP enables a clean separation of business logic from presentation. o JSP, by using Java as the scripting language, is not limited to a specific

vendor s platform.

o JSP, as an integral part of the J2EE architecture, has full access toserver-side resources.

• Because JSP pages execute on the server, you need not require the client to use

a particular browser or have a fixed configuration.

J SP vs. Pure Servlets

JSP doesn’t give anything that you couldn't in principle do with a servlet. But it ismore convenient to write and modify regular HTML than have million of println

statements.


33/75

33 | P a g e

J ava Server Pages

While there are numerous technologies for building web applications that serve

dynamic content, the one that has really caught the attention of the developmentcommunity is JavaServer Pages (JSP). And not without ample reason either. JSP

not only enjoys cross-platform and cross-Web-server support, but effectivelymelds the power of server-side Java technology with the WYSIWYG features of

static HTML pages.

JSP pages typically comprise of:

• Static HTML/XML components.

• Special JSP tags

• Optionally, snippets of code written in the Java programming language called"scriptlets."

Consequently, you can create and maintain JSP pages by conventionalHTML/XML tools.

It is important to note that the JSP specification is a standard extension defined ontop of the Servlet API. Thus, it leverages all of your experience with servlets.

There are significant differences between JSP and servlet technology. Unlikeservlets, which is a programmatic technology requiring significant developer

expertise, JSP appeals to a much wider audience. It can be used not only bydevelopers, but also by page designers, who can now play a more direct role in

the development life cycle.

Another advantage of JSP is the inherent separation of presentation from content

facilitated by the technology, due its reliance upon reusable componenttechnologies like the JavaBeans component architecture and Enterprise JavaBeans

technology.

§ Recommended Web access layer for n-tier architecture.§ Completely leverages the Servlet API.

J SP Syntax Basics

JSP syntax is fairly straightforward, and can be classified into directives, scriptingelements, and standard actions.

Directives

JSP directives are messages for the JSP engine. They do not directly produce any

visible output, but tell the engine what to do with the rest of the JSP page. JSPdirectives are always enclosed within the tag. The two primarydirectives are page and include.

Page Directive


35/75

35 | P a g e

Typically, the page directive is found at the top of almost all of your JSP pages.There can be any number of page directives within a JSP page, although the

attribute/value pair must be unique. Unrecognized attributes or values result in atranslation error. For example,

makes available the types declared within the included packages for scripting and

sets the page buffering to 16K.

Include Directive

The include directive lets you separate your content into more manageable

elements, such as those for including a common page header or footer. The pageincluded can be a static HTML page or more JSP content. For example, the

directive:

can be used to include the contents of the indicated file at any location within the

JSP page.

Declarations

JSP declarations let you define page-level variables to save information or definesupporting methods that the rest of a JSP page may need. While it is easy to get

led away and have a lot of code within your JSP page, this move will eventuallyturn out to be a maintenance nightmare. For that reason, and to improve

reusability, it is best that logic-intensive processing is encapsulated as JavaBeancomponents.

Declarations are found within the tag. Always end variabledeclarations with a semicolon, as any content must be valid Java statements:

You can also declare methods. For example, you can override the initialization

event in the JSP life cycle by declaring:


36/75

36 | P a g e

Expressions

With expressions in JSP, the results of evaluating the expression are converted toa string and directly included within the output page. Typically expressions are

used to display simple values of variables or return values by invoking a bean'sgetter methods. JSP expressions begin within tags and do not include

semicolons:

Scriptlets

JSP code fragments or scriptlets are embedded within tags. This Javacode is run when the request is serviced by the JSP page. You can have just about

any valid Java code within a scriptlet, and is not limited to one line of sourcecode. For example, the following displays the string "Hello" within H1, H2, H3,and H4 tags, combining the use of expressions and scriptlets:


37/75

37 | P a g e

J SP Implicit Objects

As a convenience feature, the JSP container makes available implicit objects thatcan be used within scriptlets and expressions, without the page author first havingto create them. These objects act as wrappers around underlying Java classes or

interfaces typically defined within the Servlet API. The nine implicit objects:

1. request: represents the HttpServletRequest triggering the service invocation.

Request scope.2. response: represents HttpServletResponse to the request. Not used often by

page authors. Page scope.

3. pageContext: encapsulates implementation-dependent features inPageContext. Page scope.

4. application: represents the ServletContext obtained from servlet configurationobject. Application scope.

5. out: a JspWriter object that writes into the output stream. Page scope.6. config: represents the ServletConfig for the JSP. Page scope.7. page: synonym for the "this" operator, as an HttpJspPage. Not used often by

page authors. Page scope.

8. session: An HttpSession. Session scope.9. exception: the uncaught Throwable object that resulted in the error page beinginvoked. Page scope.


38/75

38 | P a g e

Servlets

The Java Servlet API allows a software developer to add dynamic content to a

Web server using the Java platform. The generated content is commonly HTML, but may be other data such as XML. Servlets are the Java counterpart to non-Java

dynamic Web content technologies such as PHP, CGI and ASP.NET. Servlets canmaintain state across many server transactions by using HTTP cookies, session

variables or URL rewriting.

The Servlet API, contained in the Java package hierarchy javax.servlet, definesthe expected interactions of a Web container and a servlet. A Web container is

essentially the component of a Web server that interacts with the servlets. TheWeb container is responsible for managing the lifecycle of servlets, mapping a

URL to a particular servlet and ensuring that the URL requester has the correctaccess rights.

A Servlet is an object that receives a request and generates a response based onthat request. The basic servlet package defines Java objects to represent servlet

requests and responses, as well as objects to reflect the servlet's configuration parameters and execution environment. The package javax.servlet.http defines

HTTP-specific subclasses of the generic servlet elements, including sessionmanagement objects that track multiple requests and responses between the Web

server and a client. Servlets may be packaged in a WAR file as a Web application.

Servlets can be generated automatically by JavaServer Pages (JSP) compiler, oralternately by template engines such as WebMacro. Often servlets are used in

conjunction with JSPs in a pattern called "Model 2", which is a flavor of themodel-view-controller pattern.

The Servlet lifecycle consists of the following steps:

1. The Servlet class is loaded by the container during start-up.2. The container calls the init() method. This method initializes the servlet

and must be called before the servlet can service any requests. In the entirelife of a servlet, the init() method is called only once.

3. After initialization, the servlet can service client-requests. Each request isserviced in its own separate thread. The container calls the service()

method of the servlet for every request. The service() method determinesthe kind of request being made and dispatches it to an appropriate method

to handle the request. The developer of the servlet must provide animplementation for these methods. If a request for a method that is not

implemented by the servlet is made, the method of the parent class iscalled, typically resulting in an error being returned to the requester.

4. Finally, the container calls the destroy() method which takes the servletout of service. The destroy() method like init() is called only once in the

lifecycle of a Servlet.

Servlet containers

A Servlet container is a specialized web server that supports Servlet execution. Itcombines the basic functionality of a web server with certain Java/Servlet specific

optimizations and extensions – such as an integrated Java runtime environment,and the ability to automatically translate specific URLs into Servlet requests.

Individual Servlets are registered with a Servlet container, providing the containerwith information about what functionality they provide, and what URL or other

resource locator they will use to identify themselves. The Servlet container is thenable to initialize the Servlet as necessary and deliver requests to the Servlet as

they arrive. Many containers have the ability to dynamically add and remove

Servlets from the system, allowing new Servlets to quickly be deployed orremoved without affecting other Servlets running from the same container.Servlet containers are also referred to as web containers or web engines.

Like the other Java APIs, different vendors provide their own implementation ofthe Servlet container standard. For a list of some of the free and commercial web

containers, see the list of Servlet containers. (Note that 'free' means that non-commercial use is free. Some of the commercial containers, e.g. Resin and Orion,

are free to use in a server environment for non-profit organizations).

MVC Architecture

The main aim of the MVC architecture is to separate the business logic and

application data from the presentation data to the user.

Here are the reasons why we should use the MVC design pattern.

1. They are resuable : When the problems recurs, there is no need to invent anew solution, we just have to follow the pattern and adapt it as necessary.

2. They are expressive: By using the MVC design pattern our application becomes more expressive.

1). Model: The model object knows about all the data that need to be displayed.It is model who is aware about all the operations that can be applied to transform

that object. It only represents the data of an application. The model representsenterprise data and the business rules that govern access to and updates of this

data. Model is not aware about the presentation data and how that data will bedisplayed to the browser.

2). View : The view represents the presentation of the application. The viewobject refers to the model. It uses the query methods of the model to obtain thecontents and renders it. The view is not dependent on the application logic. It

remains same if there is any modification in the business logic. In other words, wecan say that it is the responsibility of the of the view's to maintain the consistency

in its presentation when the model changes.

3). Controller: Whenever the user sends a request for something then it alwaysgo through the controller. The controller is responsible for intercepting therequests from view and passes it to the model for the appropriate action. After the

action has been taken on the data, the controller is responsible for directing theappropriate view to the user. In GUIs, the views and the controllers often work

very closely together.

Features of MVC2:

1. The MVC2 architecture removes the page centric property of MVC1architecture by separating Presentation, control logic and the application state.

2. In MVC2 architecture there is only one controller which receives all therequest for the application and is responsible for taking appropriate action in

response to each request.

Apache Tomcat

The Apache HTTP Server, commonly referred to simply as Apache, is a webserver notable for playing a key role in the initial growth of the World Wide Web.

Apache was the first viable alternative to the Netscape CommunicationsCorporation web server (currently known as Sun Java System Web Server), and

has since evolved to rival other Unix-based web servers in terms of functionalityand performance.

Apache is developed and maintained by an open community of developers under

the auspices of the Apache Software Foundation. The application is available fora wide variety of operating systems, including UNIX, FreeBSD, Linux, Solaris,

Novell NetWare, Mac OS X, Microsoft Windows, OS/2, TPF, and eComStation.Released under the Apache License, Apache is characterized as free software and

open source software.

Since April 1996 Apache has been the most popular HTTP server on the WorldWide Web. As of June 2008[update] Apache served 49.12% of all websites.

FeaturesApache supports a variety of features, many implemented as compiled moduleswhich extend the core functionality. These can range from server-side

programming language support to authentication schemes. Some commonlanguage interfaces support mod_perl, mod_python, Tcl, and PHP. Popular

authentication modules include mod_access, mod_auth, and mod_digest. Asample of other features include SSL and TLS support (mod_ssl), a proxy

module, a useful URL rewriter (also known as a rewrite engine, implementedunder mod_rewrite), custom log files (mod_log_config), and filtering support

(mod_include and mod_ext_filter).

Popular compression methods on Apache include the external extension module,mod_gzip, implemented to help with reduction of the size (weight) of web pages

served over HTTP. Apache logs can be analyzed through a web browser usingfree scripts such as AWStats/W3Perl or Visitors.

Virtual hosting allows one Apache installation to serve many different actual

websites. For example, one machine, with one Apache installation couldsimultaneously serve www.example.com, www.test.com, test47.test-

server.test.com, etc.


42/75

42 | P a g e

Apache features configurable error messages, DBMS-based authentication

databases, and content negotiation. It is also supported by several graphical userinterfaces (GUIs) which permit easier, more intuitive configuration of the server.

UsageApache is primarily used to serve both static content and dynamic Web pages onthe World Wide Web. Many web applications are designed expecting the

environment and features that Apache provides.

Apache is the web server component of the popular LAMP web server applicationstack, alongside MySQL, and the PHP/Perl/Python (and now also Ruby)

programming languages.Apache is redistributed as part of various proprietary software packages including

the Oracle Database or the IBM WebSphere application server. Mac OS X

integrates Apache as its built-in web server and as support for its WebObjectsapplication server. It is also supported in some way by Borland in the Kylix andDelphi development tools. Apache is included with Novell NetWare 6.5, where it

is the default web server.

Apache is used for many other tasks where content needs to be made available ina secure and reliable way. One example is sharing files from a personal computer

over the Internet. A user who has Apache installed on their desktop can putarbitrary files in the Apache's document root which can then be shared.

Programmers developing web applications often use a locally installed version of

Apache in order to preview and test code as it is being developed.

Microsoft Internet Information Services (IIS) is the main competitor to Apache,trailed by Sun Microsystems' Sun Java System Web Server and a host of other

applications such as Zeus Web Server. Some of the biggest web sites in the worldare run using Apache. Google's search engine front end is based on a modified

version of Apache, named Google Web Server (GWS). Several Wikimedia projects also run on Apache servers.

Testing Methodology

Testing is vital for the success of the system. Software testing reviews the

specification, design and coding of the system and helps in software qualityassurance. It focuses on finding operational flaws in the system. So that the

software becomes error-free and prevents failure.

Testing is a process of executing a program with the intent of finding an error. Agood test is one that has a high probability of finding a yet undiscovered error.

Thus, systematic test should be carried out that uncovers different types of errorwith minimum amount of time and effort.

Testing is also carried out to see if the performance requirements have been met.Testing is also a good indication for software reliability.

Testing is carried out at various stages. In this project, I did unit testing and

system testing during the testing phase.

Unit Testing

Unit testing is performed on the smallest unit of software design – the modules.Unit testing gives stress on the modules independently of one another, to find

errors. A program unit is usually small enough for the programmer to test it ingreat detail. Unit testing helps in detecting errors in coding and logic that are

contained within the module.During the unit testing phase, various modules in the developed system were

tested separately. For example, in the data entry module, the sample data was fed

into this module to check whether all the validations that are applied on inputforms are working properly or not. Unit testing also helped me in finding outwhether the data was properly saved in the database or not. Likewise, this testing

method was applied on the modification, deletion, search, pay slip generation andreport modules.

Some of the tests carried during unit testing phase were:

Peak Load Test: The test determined whether the system can handle the volumeof activities that occur when the system is at the peak of its processing. All the

modules passed this test.

Procedure Test: This test helped in checking the specified operating conditions,input values and expected results

Performance Test: The test checked the response time, execution time andthroughput time of the modules.


73/75

73 | P a g e

Recovery Test: The test helped in verifying the ability of the system to recoverfrom failure. Some changes were made in the modules to fulfill this test

requirement.

Storage Test: It helped in checking whether the transaction data was properly being saved on the disk or not. Changes were made in the modules according to

this test’s results.The unit testing helped in finding out which module of the system is not working

as desired. Accordingly, changes were made and then the modules were testedagain, until they were up to the expected standard.

System Testing

During system testing phase, all the sub-systems are gathered and a test isconducted to determine whether the whole system meets the user requirements. A

system is tested for online responses, volume of transactions, stress, recoveryfrom failure and usability.

System testing involves two kinds of activities.

Integration Testing: Integration testing is of two kinds – Bottom-Up integrationand Top-Down Integration. For this system, Bottom-Up Integration Testing was

carried out.Bottom-up Integration is the traditional strategy used to integrate the components

of a software system into a functioning whole. Bottom-up integration consists of aUnit Testing, followed by the Sub-System Testing, and testing of the entire

system. Unit testing has the goal of discovering errors in the individual modulesof the system. The primary function of Sub-System testing is to verify operation

of the interface between the modules in the sub-system. System testing isconcerned with the decision-logic, control flow, recovery procedures, capacity

and timing characteristics of the entire system.

User Acceptance Testing: The user acceptance test verifies that the system’s procedures operate up to system’s specifications and that the integrity of the data

is maintained. It involves the execution of Procedure Test, Performance Test andPeak-Load Test. It demonstrates that the system satisfies all the user requirements

Limitations

• The project can be best viewed on Firefox. • It provides banking facilities to personal banking. • Enterprise Java Beans have not been implemented. • SSL is not implemented. • Loan facilities, credit card login is not being provided.

Future Enhancements

The Online Banking project can be enhanced in future, which will increase thecredibility and reliability of the website. The enhancements could be done byadding credit checks generating credit card statements. The enhancements that

could be done are as follows:

• It can be implemented fully on the Internet by registering a domain and buyinga web space.

• It can provide the Credit card bill payment option.

• It can provide user loan facilities with interest rates in accordance with bank to.

• It can be merged with other e-commerce websites for providing a gateway to

pay through credit cards .
