Presentation UCS2722 Object Oriented Systems Development

The uploaded document is a comprehensive set of lecture notes on **Object-Oriented Analysis and Design (OOAD)**, designed to provide a thorough understanding of OOAD principles, methodologies, and applications in software engineering. It begins by addressing the complexity of software systems and emphasizes the need for OOAD to manage this complexity through hierarchical systems and abstraction. The notes explore object-oriented systems development, highlighting key concepts such as classes, objects, inheritance, encapsulation, abstraction, and polymorphism, alongside their advantages like flexibility, robustness, and reusability. A significant portion focuses on the Unified Modeling Language (UML), covering both structural and behavioral diagrams such as class diagrams, sequence diagrams, use case diagrams, and state machine diagrams, with practical examples like e-commerce and library management systems. It delves into use case-driven analysis, explaining the importance of use case diagrams, relationships like `<<include>>` and `<<extend>>`, and their role in capturing requirements. Additionally, the document discusses domain modeling and class diagrams, providing insights into relationships such as association, aggregation, composition, and inheritance, and their use in creating solution-independent representations of problem domains. It also covers object-oriented methodologies, including Rumbaugh’s OMT, Booch’s methodology, and Jacobson’s OOSE, and their integration into the UML framework. Lastly, the notes emphasize software quality assurance (SQA) processes to ensure software meets quality standards through testing, verification, and validation. With its practical examples, detailed diagrams, and methodological insights, the document is a valuable resource for students and professionals seeking expertise in OOAD.
