Requirements Analysis and System Design

Do you want to design cutting-edge enterprise information systems? Do you want to learn the principles, methods and techniques behind successful analysis and design and be able to put this theory into practice? The second edition of this best-selling book will guide you through this process, helping you deal with the challenges involved, to develop large-scale object-oriented systems in an iterative and incremental way. The approach, further built on in this new edition, is distinctive because it:

• relates theory to reality, with practical problems and limitations that would have to be addressed in the real world;
• pays special attention to the design phase, acknowledging the difficulties and intricacies of large-scale system development; and
• provides an enormous number of non-trivial examples and exercises.

The case studies and tutorials that will help you learn by example have been taken from the following varied application domains: online shopping, advertising expenditure, contact management, time logging, telemarketing, university enrolment and video store. Each has its own unique features and educational benefits. The second edition has been substantially updated, broadening the coverage and ensuring the book is up-to-date in the technology-influenced area of systems development. Key changes from the last edition are:

• use of UML 2.0 and occasional use of Java code to further explain the meaning of more complex UML models;
• a "crash course" on object technology and object modeling, following requirements analysis and prior to requirements specifications with UML;
• a "crash course" on system architecture and program design prior to the detailed discussion about distributed client/server system design;
• a new discussion about user interface design with user experience (UX) storyboards and discussing the mapping between business objects and relational databases; and
• significant expansion of the guided tutorial on online shopping, making this a separate chapter for review and reinforcement at the end of the book.

Whether you are a student on a computer science or information systems course, or someone working in industry-wanting up-to-date practical help based on a sound theoretical footing, this book will be of lasting benefit to you.
