It includes detailed coverage of modelling techniques and notation, with worked examples throughout. The book contains substantial code examples in Java. It clearly connects design concepts with code, and is useful for people with programming experience who wish to learn about design. It is also useful for computer science and software engineering undergraduates taking courses covering object-oriented techniques. The book provides explanations of UML and OCL notation emphasis on transitions from design to code, as well as including complete case studies with code, and many exercises Provides an introduction to the design of object-oriented programs using UML. This book focuses on the application of UML in the development of software, and offers a tutorial to the UML notation and its application. The book is useful for undergraduates taking modules as part of a Computer Science or Software Engineering degree programme.
