Partial Operations

Users can carry out partial issues, flushes, drops and releases on specified parts of the database.

Setting up an Extract Hierarchy

Before the user starts creating extracts and working extracts, they should have a clear plan of how they will be used. The user should maintain diagrams of the basic primary extract‑working extract database organization. These help when designing flush and release procedures, and defining MDBs.

Note:
The databases shown are all part of the same extract family, and so they will all have the same database number, for example 200.

Refer to Data Access Control (DAC) for an example of how the user might use extracts and working extracts with Data Access Control (DAC) to control work flow.
