System Analysis Design for a Library System

Suppose you are helping to develop a library system for your community. Here is a brief description of various scenarios using this library system.
• Bob wanted to become a member at his local library.

• Bob was very anxious to read "The Space Trilogy", so every day at home he would login to the library system and check the status of the book. Every
