ABSTRACT

Our project “ATM SYSTEM “ help the users to do banking easily through online access.

The system is so beneficial that it helps the users to know about the account balance and other

transactions. Through this system the user can perform various transactions like deposit,

withdrawal etc.

After the transaction is over, the user can check the balance amount he has in his account.

Thus the transaction details are maintained. He can withdraw more amounts if he wishes. Here is

also a limit associated with a particular user as to how many times he can log on to his account.

The corresponding updating of balance will be made automatically on the main database.

SCOPE OF THE SYSTEM

The following subsection describes the scope of new ATM SYSTEM in terms of

its audience and organization.

AUDIENCE

The intended users are the people responsible for implementing ATM SYSTEM.

ORGANIZATION

This document describes the new ATM system requirements in terms of system

requirements, executive summary, analysis and design diagrams.

ANALYSIS

PROBLEM STATEMENT

The bank client must be able to deposit an amount from his/her account using the bank

applications. Each transaction must be recorded and the client must have the ability to review all

transaction performed against A given account balance after the transaction.

A bank client can have two types of accounts namely checking account and savings

account. For each checking account, one related savings account can exit.

2 | P a g e

The application must verify that a client can gain access to her/his account by

identification via the personal id no. Neither a checking nor a savings account can have a

negative balance. The application should automatically withdraw amount on the checking

account is more than its current balance.

If the savings account balance is insufficient to cover the request withdraw amount, the

application should inform the user and terminate the application.

ASSUMPTIONS

Access to the bank client is provided by a pin code consisting of 4 integers between 0 and

9 numbers.

One pin code allows access to all account held by a bank client.

No receipt will be provided for any account transactions.

The bank application operates for a single banking institution only.

There is no automatic transfer from a related checking account to a savings account. If

the balance on a savings account is less than the withdrawal amount request the

transaction. The transaction will stop and bank client will be notified.

DESIGN – RATIONAL ROSE

INTRODUCTION TO DIAGRAMS

Rational rose is a design tool used to depict our project in the form of diagrams so that

the user can easily understand the project.

USE CASE DIAGRAM

Use - case diagrams graphically depict system behavior. These diagrams present a high

level view of how the system is used as viewed from an outsider’s perspective. A use-case

diagram may depict all or some of the use cases of a system. A use-case diagram may contain:

Actors

Use cases

Interaction or relationships between actors and use cases in the system including the

associations, dependencies and generalizations.

CLASS DIAGRAMS

The class diagram allows you to add, retrieve and delete classes and categories to and

from a class diagram. The class diagram class has a set of properties and methods that apply

specially to class diagrams,

SEQUENCE DIAGRAM

A sequence diagram is a graphical view of a scenario that shows object interaction in a

time based sequence ¾ of what happens first, what happens next. Sequence diagrams establish

the roles of the objects and help in proving essential information to determine class

responsibilities and interfaces. This type of diagram is best used during analysis phases in design

because they are simple to comprehend. Sequence diagrams are normally associated with the use

cases.

COLLABORATION DIAGRAM

A collaboration diagram provides a way to model the workflow of a business process.

Activity diagrams are very similar to flowchart because you can model a workflow because you

can model a workflow from activity to activity.

ACTIVITY DIAGRAM

Activity diagram provides a way to model the workflow of a business process. These are

similar to flowchart because you can model a workflow from activity to activity.

COMPONENT DIAGRAM

Component diagrams provide a physical view of the current model. It shows the

organizations and dependencies among software components, including source code

components, binary code components and executable components. These diagrams also show the

externally visible behavior of the components.

DEPLOYMENT DIAGRAM

A deployment diagram shows processors, devices and connections. Each model contains

a single deployment diagram, which shows the connections between its processors to processors.

FORWARD ENGINEERING

1. Design the use case diagram, sequence diagram, collaboration diagram, class diagram,

activity diagram, component diagram, deployment diagram for On-line reservation

system.

2. Go to the component view and select anyone relevant component in the component

diagram and choose open specification and select general tab and set the language as

ANSI C++ and press apply.

3. Right click the same component and choose “open specifications” and click the realize

tab and then assign the classes which are listed.

4. Select the same component in the browser window, right click and choose ANSI C++ and

then click generate code. The dialog window specifies the directory path where the

header files and the C++ files are stored and press ok.

5. All the required files will be generated in the specified directory if any change is done in

the code diagram, do the above step.

14 | P a g e

REVERSE ENGINEERING

1. Type the cpp program in ANSI C++ software and save the file.

2. Open rational rose. Go to browse menu, create a class diagram and place the class.

3. Give the class name as one of the class name as you defined in cpp file (Turbo C++).

4. Go to browse menu, create a component diagram and place the component in that

component diagram.

5. Go to the component view and select anyone relevant component in the component

diagram and choose open specification and select general tab and set the language as

ANSI C++ and press apply.

6. Right click the same component and choose “open specifications” and click the realize

tab and then assign the classes which are listed.

7. Select the same component in the browser window, right click and choose ANSI C++ and

then click generate code. The dialog window specifies the directory path where the

header files and the C++ files are stored and press ok.

8. Open directory and open the header file of the class. After erasing the empty class in the

header file, copy the C++ program (typed in the ANSI C++ software), paste it and save it.

9. Come back to Rational Rose software, right click the component, Choose ANSI C++ and

click reverse engineering.

10. Open the class diagram and see the changes in the class diagram.

TESTING

TEST OBJECTIVETesting is a process of executing the programs with intend of finding errors. A good test

case is the one that has high probability of finding error. A successful test is the one that

uncovers and undiscovered error.

If testing is done successfully, it will uncover errors the software. Testing demonstrates

that software function appears to be working according to the specification that behavioral and

performs requirements appear to have me the data collected as testing is conducted to provide

good indication o software quality as a who.

TEST PLAN

Before testing is to be done, test plan must be done in order to identify which testing

method is to be implemented for the project. Test cases must be identified.

WHITE BOX TESTING

The test method used in our project is WHITE BOX TESTING. It is otherwise called as

GLASS BOX TESTING. It is a testing in which test case design method is used to control the

procedural design to derive test cases that

Guarantee that all independent paths within a module have been exercised at least once.

Exercise all logical decision on their true and false sides.

Exercise all loops at their boundaries and within their operational bounds.

Exercise internal data structures to ensure their validity.

CONCULSION

Thus the “ATM SYSTEM “developed has the essential requirements made where strictly

followed. The system was tested vigorously with simple data for all possible errors. The

encountered errors were set right. A good amount of user friendly features have been

incorporated in the system and it is possible for any user to exploit these features to the

maximum benefit.
