Data analysis for database design is a subject of practical value to systems analysts and designers. This third edition has been updated to ensure that developments concerning relational databases are included. In particular, there is a new section on the object-orientated approach and a detailed case study outlining the use of SQL in first and second level design. The book explains techniques from a practical standpoint by using small-scale realistic examples and "answer pointers" at the end of each chapter to encourage understanding. The questions and assignments have also been updated for this third edition, as have hardware aspects.
