1.0 Introduction
1.1 Purpose:
The web based blood donation system is mainly uses for helping the patient who
need blood. So this SRS document consists of a simple explanation about the system
and its features. The document mainly focuses on providing sufficient design
information to the blood donorauthorities. And also it will satisfy the functional,
design, performance requirements of the system in briefly.
1.2 Objective:
This system presents an alert system to the donorabout requirement of their blood
to a person need and also provide online status of blood group wise
availability of blood unit.

2.0 Problem Definition of Existing system
Entering the details about the blood groups, members, addresses etc. And tracking the
database is complicated when the details are maintained manually. This makes the
maintenance of schedule erroneous. Limitation of manual system. It is time
consuming. Retrieval of data takes lots of time. It lacks of data security. Reports takes
time to produce. Percentage of accuracy is less.
3.0 Proposed System
This system is used for maintain whole information about blood. In this project
mainly 3 modules are there:
 Admin
 Donor
 User
