Using Working Extracts

Administrator User Guide

Multiwrite Databases and Extracts : Working Extracts : Using Working Extracts

Working extracts are largely invisible to users, although users will need to be aware that they are using extracts, and that they will need to use the normal extract controls (flushing, releasing, etc.).

If you are working with extracts, the normal way of working is to create working extracts for the users who are actually creating data. Intermediate levels of extract will normally be used for checking, approval etc.

Working extracts are always 'implicit', so there is no need to use the CLAIM/UNCLAIM commands (which have no real meaning when using working extracts). Similarly, Q CLAIMLIST has little meaning, other than to indicate what the user is currently working on. A user should always use Q CLAIMLIST EXTRACT when using working extracts, to check what is claimed to the working extract and, hence, what is truly claimed to that user.

Important:

It is strongly recommended that users should work either totally with working extracts or totally without.
