Component based software engineering
The document describes the component level design of a library circulation system. It outlines various classes and their attributes that would make up such a system, including classes for User, Item, Report, Fine, and others. Sequence diagrams and flowcharts are provided showing the logic and flow of key processes like issuing an item, returning an item, and calculating overdue fines.
