Author Description

The development of a software system takes place in three iterative and incremental phases - analysis, design and implementation. This book describes the methods and techniques used for analysis and design, with implementation issues addressed to the extent to which they must be considered in the design. The text concentrates on object-oriented software development, using the Unified Modeling Language (UML). The book uses the teach-by-example principle - all concepts are exemplified and the running case studies present integrated solutions.The focus of the book is on developing large-scale, client/server, multi-tier object-oriented information systems. The client is a workstation with a GUI and the server manages a database. The client, server and middle-tier processes communicate via object messaging. The server database can be relational, object-relational or purely object-oriented. The book identifies ways to:* integrate analysis and design models;* harness the complexity of large system models;* improve software architectures;* promote layered structuring of objects;* understand consequences of reckless modeling;* conduct testing and manage change;* build maintainable and scalable systems.The book can be used for undergraduate courses in computer science or information systems such as systems analysis, systems design, software engineering, databases and object technology, as well as being a valuable resource for software projects. The book has also been written for professionals developing business information systems, such as IT managers, application developers, consultants, analysts, designers, programmers, testers, software engineers, systems integrators and educators. The text is accompanied by a comprehensive website that contains a wealth of additional material for instructors, students and professionals.
