System analysis is a process of gathering and interpreting facts, diagnosing problems and the
informationtorecommendimprovementsinthe system.Itisa problem-solvingactivitythatrequires
intensive communication between the system users and system developers. System analysis or
study is an important phase of any system development process. The system is studied to the
minutestdetail andanalyzed.The systemanalystplaysthe role of the interrogator and dwells deep
intothe workingof the presentsystem.The systemisviewedasawhole andthe inputto the system
