To analyze the problem gather the requirements and implement online Banking System and to model the data using UML diagram.
Phase 1: Problem analysis:
The customer inserts the account number in to software. If the pin no is valid the account is opened else rejected. The customer should select to account and type the registered amount be wished withdraw or withdraw. The program checks the amount is available in His account and issues the cash and should update the amount and the transaction in the account.
Phase 2:
Functional Requirement analysis:
Customer: External entity to the system and entities initiates the withdraw process from the bus.
Clerk : This is the system on its responsible to response for each events caused by the user.
Cashier : The hold updates and manipulates both user details and all details.
Phase 3:
The various data modeling techniques which are implemented in the ATM system are
Use case diagram
Class diagram
Collaboration diagram
Sequence diagram
State chart diagram
Activity diagram
Component diagram
Phase 4:
The software is now designed in rational rose and skeleton code is generated in VB
Phase 5:
Implementation:
ATM use case diagram
ATM class diagram
ATM sequence diagram
ATM state chart diagram
ATM component diagram
