Multiwrite Databases and Extracts : Using Extracts : Partial Operations

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

Before you start creating extracts and working extracts, you should have a clear plan of how they will be used. You should maintain diagrams of the basic master extract‑working extract database organisation. 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 you might use extracts and working extracts with data access control (DAC) to control work flow.
