This course has been specifically designed to provide a thorough introduction to Db2 for z/OS, and covers all features up to and including V 12.<br>Taught from a Technical Support/Computer Operations perspective, 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 comprises formal classroom tuition along with a series of demonstrations and practical, hands-on exercises that reinforce the students' understanding at every stage.<br><br>This course is also available for one-company, on-site presentations and for live presentation over the Internet, via the Virtual Classroom Environment service.
