BMC Mainframe: Db2 for z/OS -  Introduction, Concepts & Facilities

The course is developed and delivered by © RSM Technology.

This course introduces, describes, and explains the fundamental principles of Db2 for z/OS. The course also explains the relational theory and concepts and shows how Db2 adheres to them. The concepts of Db2 data storage, the Db2 system and its operation, Structured Query Language, the use of DB2 Interactive (DB2I), and the management of Db2 data using standard utility tasks are also introduced and explained. The course includes demonstrations and practical, hands-on exercises, and is relevant to all releases of Db2 for z/OS.
