BANK MANAGEMENT SYSTEM

PROBLEM STATEMENT:

A Banking concern by the name ABC Bank wants

to computerize its Banking Services. Bank Management isgenerally a very complicated task. To reduce the complexity,it wants to computerize its Banking services and for thispurpose it wants software, which will handle all itstransactions.

The software created must get the overallinformation from the user. It should then give the user anoption as to whether the user wants to make a withdrawal ora deposition.

As the bank for which the software is to be createdprovides loan and locker facilities, the various activities ofhandled by the bank is provision of loan, handling the lockerfacility and handling the regular banking services.

BANK MANAGEMENT SYSTEM:

PROBLEM STATEMENT:

ABC Bank a nationalized bank wants to computerize some of its services.Banking services is really a complicated task. Each service has a process of

its own to be carried out. To reduce the complexity the bank wants to

computerize some of its services like maintenance of account holders details,their transactions, providing interest for fixed deposit account holders etc.

The software created must get the information from theuser. It should then give the user an option as what he wantsto look into, like the details of the account holder, his

transactions, interest calculated etc by selecting onto thecorrect option.

As the firm for which the software is to be createdis a Bank, the various activities of the bank which thesoftware must carry out is maintenance of account holdersdetails, their transactions, interest calculation for fixeddeposit account holders etc. The software created mustallow the user to view the details of the account holder foreach activity.

FUNCTIONAL POINT ANALYSIS

Bank management system

Function oriented software metrics measure of the functionality

delivered by the application as a normalization value. Function oriented

metrics were first proposed by Albrecht [ALB79], who suggested a measure

called the function point. Function points are derived using an empirical
