Many IT systems require historical data to be kept, in addition to the current status information. Db2 10 for z/OS introduced temporal data support to provide this functionality, whereby the historical data is automatically maintained. This intensive course provides an in-depth look at how temporal tables may be created and exploited. This course also covers the concept and usage of archive tables, as introduced with Db2 11 for z/OS.

A good understanding of Db2 and experience of using SQL.
