Functional architecture overview

You will need to understand the functional architecture for data events.

Commit Capture

This captures data events coming through online. This will only happen if the application has been enabled for Relational Replication.

Extract

This does the following:

1. Creates jobs.
2. Polls data events captured by Commit Capture.
3. Puts these data events into Relational Replication staging tables.

Data Transform

This parses and converts the data events into table column format using metadata.

Load

This does the following:

1. Generates DML statements from the staging tables.
2. Loads these DML statements into Relational Replication target tables.
3. When an event has been processed, it updates the Process Status in the staging table.
