Course Description:
This subject provides an in-depth look at DB2 Universal Database for the AS/400, the most widely used multi-user relational database in the world. This subject will start with a brief look at the native interface which includes logical, physical and field reference files and then focus on the SQL/400 interface which includes Data Definition Language, Data Manipulation Language, Embedded SQL/400, Stored Procedures and the SQL Procedure language, Journaling and Commitment Control and ODBC. Advanced topics include Database Constraints, File Overrides, Trigger Programs, Database security, Backup and Recovery, the Universal Database and Operations Navigator.
