Rather than focusing on a specific software title, the authors explain the theories which are true for any system, and so provide a solid and structured background for aspiring software developers to build upon. With a new design and new features within the text, Software Systems Development is now even easier to follow and the examples and exercises are also been restructured to improve the knowledge flow to the student.This book takes a very accessible approach to systems analysis and design, suitable for Computer Science students on any introductory course, or for those coming from other disciplines with an interest in software development. The `just-a-line' case study which runs throughout the book takes a clear line from systems design, through development to implementation and release and provides coverage of Project Management techniques and testing and crisis management. Software Systems Development is supported by an Online Learning Centre with numerous resources for students and lecturers.
