Do we know Temporal Data(DB2 Version 10 for ZOS)
Most IT systems need to keep historical as well as current information.
requirements would have involved the DBA and application developers spending valuable time creating and testing the code and while minimizing any performance impact.
DB2 10 provides this functionality as part of the database engine, making DBAs and developers more productive. All the DBA needs to do is indicate which table/columns require temporal support when they are created, and DB2 will automatically maintain the history whenever an update is made to the data. Elegant SQL support allows the developer to query the database with an "as of" date, which will return the information that was current at the specified time.
