Average Reviews:
(More customer reviews)I wish I had this book as soon as it was published. After programming on the S/38 and the AS/400 (in RPG) for over 14 years now (with some interruptions), I consider this one the best AS/400-related computing book I have purchased - ever! And compared to other computer books, well, if only that kind of quality would be available on other topics as well more frequently, either DBMS's or programming languages. The book saved one of my clients hours of work: with no previous SQL knowledge but having this book they were able to do some work with SQL that otherwise would have required them to write a program. Another client (and myself for my own system) took advantage of the chapters on Referential Integrity. If you're serious about accessing your data on your DB2/400 database, you owe it to yourself to buy this book !

Paul Conte, a leading DB2/400 authority with extensive application development experience, provides easy-to-follow instruction in the proper way to create efficient, flexible databases on the AS/400. His explanations and advice assure that you'll handle your design and coding challenges with confidence and professional-level techniques. This book provides complete coverage of both DDS, the traditional approach to defining DB2/400 files, and of SQL/400, the industry-standard database language that is IBM's strategic language for the future of DB2/400. With this text, you can be sure of handling not only existing application databases, but also developing new SQL/400 databases. These skills will put you in the forefront of AS/400 application developers. Database Design and Programming for DB2/400 also provides an excellent introduction to practical database design techniques. You get a solid introduction to the relational database model, which underlies the whole DB!2/400 architecture and the SQL language. On that foundation, the book explains a step-by-step method of modeling an organization's database requirements and developing a design for the necessary database files. The text is designed for college-level courses and for independent study. Each chapter has numerous examples and exercises. The material is organized into four parts - DDS, database design, SQL, and advanced DB2/400 features - so you can focus on particular topics as needed. Appendices provide extensive reference material. You can use the book as your single DB2/400 resource, eliminating the need for many IBM manuals. You will find Database Design and Programming for DB2/400 immediately useful, whether you're just beginning to learn DB2/400 or you are an experienced developer. You will turn to this book time and time again for advice on the best way to design and program DB2/400 databases.
