This document provides an overview of object oriented software modeling and design using the Unified Modeling Language (UML) for an airport system case study. It includes UML diagrams like use case diagrams, activity diagrams, state-activity diagrams, sequence diagrams, and class diagrams to model different aspects of the airport system at varying levels of detail and abstraction. The document was created by Dr. Abdel-Karim Al-Tamimi and covers concepts like analysis process, external vs internal views, and system and subsystem modeling.
