A Banking concern

A Banking concern by the name "BBC Bank" wants to computerize its Banking Services.

Bank Management is generally a very complicated task. To reduce the complexity, it wants to computerize its Banking services and for this purpose it wants software, which will handle all its transactions. The software created must get the overall information from the user. It should then give the user an option as to whether the user wants to make a withdrawal or a deposition.

As the bank for which the software is to be created provides loan and locker acclivities, the various activities of handled by the bank is provision of loan, handling the locker facility and handling the regular banking services. The software created must allow the user to handle each of the service provided by the bank. The software should manage the banks account at the end of the year and finally if should generate the yearly financial report of the company. BBC 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 the user. It should then give the user an option as what he wants to look into, like the details of the account holder, his transactions, interest calculated etc by selecting onto the correct option.As the firm for which the software is to be created is a Bank, the various activities of the bank which the software must carry out is maintenance of account elders' details, their transactions, interest calculation for fixed deposit account holders' etc.

The software created must allow the user to view the details of the account holder for each activity. The software should calculate the interest for fixed deposit account holders' as per the time given by the user. It should maintain every detail of the account holder. This document is to provide the software requirement specification of the computerized solutions for certain banking services. It keeps track of the account holder's details.

It calculates the interest rate for fixed deposit account holders'. 1 . 1. Purpose: The main purpose of this software is to enable the easy maintenance of account holders' details, their transaction etc.
