Object Oriented Analysis and Design with UML covers the conceptual underpinnings of object orientation. The book provides practical guidance on the analysis and design of object oriented systems and the concepts presented are based on a solid theoretical foundation. The book deals primarily with a method of software development. As such, it is appropriate for courses in software engineering and as a supplement to courses involving specific object oriented programming languages. This book introduces several tools for analysis and design, including the use of case narratives and diagrams, class diagrams, sequence and collaboration diagrams, state and activity diagrams and design pattern principles. It also covers fundamental object oriented concepts such as polymorphism, inheritance, encapsulation and interfaces. This text is appropriate for undergraduate and graduate students of IT programmes, and for those working in industry, such as programmers, IS business analysts and IS managers.
