Practical SSADM: Version 4 Book

This textbook on SSADM Version 4 covers the analysis and design of information systems from feasibility study to physical design. A standard range of techniques is applied progressively to transform raw user requirements into a detailed system specification taking the form of a set of (largely diagram based) products or models. The presentation of SSADM Version 4 in the book reflects the way in which it is used, and closely follows the development of a comprehensive central case study. Techniques are introduced as and when required, and subsequently expanded or adapted as products are refined in later steps. The text closely follows that of SSADM itself with a chapter for each stage in the project life cycle. each chapter is further divided into sections dealing with individual project steps. At the end of each section a second case study is used as the basis for exercises in which readers develop a library system specification in parallel with the main text. A suggested solution is provided in a lecturers supplement. When SSADM Version 4 requires the use of techniques outside the method, eg information gathering and cost benefit analysis, the book briefly outlines suitable methods and gives references for further reading. This text assumes no familiarity with Version 3. A fully-worked, substantial case study establishes the proper application of the method and Version 4 techniques and products are described in context, enhancing the understanding of their purpose and interdependency. A further case-study is used as the basis for exercises. It is suitable for students on HNC/D courses in business computing/computing science; information systems design degree and MSc courses; students specializing in information systems, particularly project work, and students taking the BCS Certification of Proficiency in SSADM.Read More
