The document discusses an object oriented analysis and design of a SIM issuing system, which allows customers to select SIM card and plan details, place orders, and receive bills, and maintains separate modules for customer and admin functions like adding, removing, or editing plans. It includes various UML diagrams like use case, class, sequence, state, activity, component, collaboration, and deployment diagrams that model different aspects of the SIM issuing system.
