SYSTEM DESIGN ________________________________________________

CCET (IT)87


INTRODUCTION

During analysis, the focus is on what needs to be done intendment of how it is done.

During design, decisions are made about how the problem will be solved, first at a high

level, then at increasingly detailed levels.

System design is the first stage in which the basic approach to solving the problem is

selected. During system designing the overall structure and style are decided. The system

architecture is the overall organization of the system into components called system.

System design deals with transforming the customer requirements, as described in the SRS

document, into a form that is implement able using the programming language. Certain

items such as modules, relationships among identified modules, data structures,

relationships between the data structures, and algorithms for implementation should be

designed during this phase.

As a system designer we are tried to take following design decisions:

Organize the system into modules

Organize sub-modules for each module

Allocate tasks to processors

Choose an approach to manage data store

Handle access to global resources

Choose implementation logic
