Software Requirements Specification

1.0 Introduction:

Information Technology is revolutionizing the way in which we live and work. It is changing all

aspects of our life and life style. The Digital revolution has given mankind the ability to treat information

with arithmetic precision of which computer and network communication are integral parts of the system.

A bank is a financial intermediary that accepts deposits and channels those deposits into lending activities,

either directly or through capital markets. A bank connects customers with capital deficits to customers with capital

surpluses. Banks act as payment agents by conducting checking or current accounts for customers,

paying cheques drawn by customers on the bank, and collecting cheques deposited to customers'

current accounts. Banks also enable customer payments via other payment methods such as ATM.

Banks provide almost all payment services, and a bank account is considered indispensable by most

businesses, individuals and governments. Non-banks that provide payment services such as remittance

companies are not normally considered an adequate substitute for having a bank account.

i)Support

IBS will support virtual banking environment which is fully automated, customizable and

user-friendly, available to customers through the web.

1.6 Overview: The SRS will include two sections, namely:

-I- Overall Description: This section will describe major components of

the system, interconnections, and external interfaces.

-I- Specific Requirements:This section will describe the

functions of actors, their roles in the system and the constraints

faced by the system.

2.0 Overall Description:

2.1 Product Perspective:

The client will have client interface in which he can interact with the banking system. It is a

web based interface which will be the web page of the banking application. Starting a page is

the entire system. He will also have a login page where he can enter the login particulars so that he

can perform all his actions. This administrative interface provides different environment such that

he can maintain database & provide backups for the information in the database. He can register

the users by providing them with username, password & by creating account in the database. He

can view the cheque book request & perform action to issue the cheque books to the clients.
