You may be familiar with SQL, the IBM DB2 for i data-access language. But you might not know that you can use SQL to modernize your IBM i database, to make it more efficient and easier to access. Rafael VictÃ³ria-Pereira knows firsthand how to use SQLâ€™s database modernization powerâ€”and in SQL for IBM i: A Database Modernization Guide, he shares this knowledge, explaining how you can use SQLâ€™s capabilities to modernize and enhance your IBM i database.
The book takes you on a journey: the modernization of a fictional universityâ€™s database. Youâ€™ll start with a database thatâ€™s basically a set of physical files (typical of many RPG applications), then transform it into a proper SQL database with advanced features that can be used both internally (by an RPG application, for instance) or externally (by a .NET or Java Web application).
As you progress, youâ€™ll get plenty of easy-to-understand examples and exercises to help you grasp and master the concepts, so you can use them on the job. The authorâ€™s down-to-earth style and solid knowledge of SQL on IBM i make for an absorbing, highly educational journey into IBM i database modernization.
After youâ€™ve read this book, you will know how to:
- Modernize your database, freeing it of its RPG/COBOL shackles
- Migrate your database definition from DDS (the native way) to SQLâ€™s DDL (the â€œmodernâ€ way)
- Use advanced SQL concepts, such as user-defined functions, common table expressions, and more
- Make your database easier to access
- Open your database to non-native applications by moving business rules to the database, automating data consistency checks, and more
- Use the system catalog to better understand the database and its componentsÂ Â
