Update Techniques

The main update technique for bundling database changes in a single database LUW is to use CALL FUNCTION... IN UPDATE TASK. This section describes various ways of updating the database.

A program can send an update request using COMMIT WORK

To the update work process, where it is processed asynchronously. The program does not wait for the work process to finish the update ( Asynchronous Update).

For asynchronous processing in two steps ( Updating Asynchronously in Steps.)

To the update work process, where it is processed synchronously. The program waits for the work process to finish the update ( Synchronous Update).

To its own work process locally. In this case, of course, the program has to wait until the update is finished ( Local Update.)
