CSC 480 Software Engineering

This document explores the foundational concepts of Object-Oriented (OO) modeling in software engineering, focusing on static and dynamic models. It covers essential topics such as class members, attributes, operations, and structural relationships like inheritance, aggregation, and composition. Case studies, including the Punch-in Info program, illustrate practical applications of UML notations, use case diagrams, sequence diagrams, and statechart diagrams to model system behavior and structure effectively. Gain insights into organizing and structuring software systems through these visual tools.
