Introduction

After analyzing the problem, one must decide how to approach the system design. During
system design developers devise the high-level strategy (system architecture) for solving the
problem and building a solution and make decisions about the organization of the system into
subsystems, the allocation of subsystems to hardware and software and major policy decisions
that form the basis for class design. System design is the first design state for devising the basic
approach to solving the problem. During system design, developers decide the overall structure
