ABSTRACT:

The expansion of ATM is Automated Teller Machine. ATM is used for money transferring purpose. The client should have account in ATM system as well as in bank.

The process is as follows first insert ATM card into ATM machine.

After inserting the ATM card enters the pin number, card reader reads the pin number, and machine asks their corresponding password(pin code) to the client.

The pin code must be within four digits. If the pin code is valid, the client can perform their corresponding operations on his account, otherwise appropriate message will be displayed to the client.

After that client entered the password and choose the options that are displayed in the moniter. The options are enquiry,withdraw, transaction and exit.

Once the client chooses their required option, the details regarding that particular options are entered. Client details will be displayed on the screen.

REQUIREMENT ANALYSIS:

In this requirement analysis , the ATM system’s requirement specification is described in detail . The clint details and account details are the basic requirements of this project.

There are three operations to be performed here,

1.Login

2.Withdrawing of money

3. Transaction history

ABOUT REQUISTE PRO:

Rational requiste pro stores the requirement documented under dynamically linked database.The user can communicate , collaborate and provide updates on the same project.

There can be several requiste project with one requiste pro database , each one associated with a separate Rational project.However there can be only one relational project associated with each requiste pro project.

Analysing requirements with different views:

After crating the package and Requirement types the user can analyse the requirements in a View.

1.ATTRIBUTE MATRIX:

It provides the precise visualization of requirements , priorities ,cost,status and unique id created for each of these.

2.TRACEABILITY MATRIX:

It is a two dimensional with rows and columns for requirement type selected.This is a pictorial view of hierarchy in which the users analyse.

3.TRACED INTO:

This is an extension of traceability matrix where only the requirements that is traced to their parent.It is viwed in the form of tree.

4.TRACED OUT OF:

This is another extension of traceability tree in which only the requirements that trace their child are depicted.

DESIGN:

Design has a great impact on the overall success of the software development project. A large pay off is associated with creating a good design “ upfront “, before writing a single line of code.While this is true of all programming classes and objects underscore the approach even more good design usually simplifies the implementation and maintenance of a project.

During design phase , we must evaluate the model into actual objects that can perform the required task. Ther is a shift in emphasis from the application domain to implementation.The classes are identified during analysis provide as a framework for the design phase.

ABOUT RATIONAL ROSE:

Rational Rose enables visual modeling of architecture components and data using Unified Modeling Language ( UML ). It is a graphical representation of a software system.It automatically implements the framework of our code in a popular language and automates.The process of maintaining consistency between a software model and its implementation.

A Rose model can be associated with more than one relational project and multiple Rose models can be associated to same rational project.

It shares visual model for business process software components , classes and objects.

The user can model the following five basic diagrams in logical view.

1.Use case Diagram

2.Class Diagram

3.Sequence Diagram

4.Collaboration Diagram

5.Activity Diagram

The user can also model the other diagrams

1. State chart diagram

2. Component diagram

3. Deployment diagram

IMPLEMENTATION:

CODING:

FORM 1:

Private Sub Command1_Click()

Text2.Visible = True

Label2.Visible = True

Command2.Visible = True

End Sub

Private Sub Command2_Click()

If Text2.Text = 1234 Then

Form2.Show

Else

MsgBox ("enter correct password")

End If

End Sub

Private Sub Timer1_Timer()

Text3.Text = Time

Text4.Text = Date

End Sub

FORM 2:

Private Sub Command2_Click()

Command2.Visible = False

Command3.Visible = False

MsgBox "YOUR BALANCE IS 15685.89"

End Sub

Private Sub Command3_Click()

Command2.Visible = False

Command3.Visible = False

Command4.Visible = True

Command5.Visible = True

End Sub

Private Sub Command4_Click()

Label1.Visible = True

Text1.Visible = True

Command6.Visible = True

Command4.Visible = False

Command5.Visible = False

End Sub

Private Sub Command6_Click()

MsgBox "COLLECT UR CASH AND RECEIPT"

End

End Sub

Private Sub Timer1_Timer()

Text2.Text = Time

Text3.Text = Date

End Sub

OUTPUT:

CONCLUSION:

Thus the program is analysed, designed, implemented and tested for an ATM. This project provides efficient money transition between the customer and the bank.

Further ATM also allows only the authenticated users. Thus the security level is very high. It also ensures the user reliability.

As the project is implemented using object oriented concept, further changes can be made easily and more utilities can be added.

Finally there is no doubt that as the modifications are updated immediately, this project will exist in the future, with many more additional facilities.
