Editing the Source Schema
Data replication apps replicate selected entities from the source system to the target database. Your source system might change from time to time with fields being added or changed or new entities being added. In general, changes to the source system are mirrored in the target database, as follows:
- If a new field is added to a source entity that is being replicated, the new field is added to the corresponding table in the target database the next time the app runs.
- If a field is removed from a source entity that is being replicated, that field is NOT removed from the target database.
- If the properties of a source field are changed, TIBCO Cloud™ Integration - Connect attempts to make the same changes in the target database.
- When the size of a text field is reduced in the source, the corresponding text field in the target is NOT shortened.
- When the size of a text field is expanded in the source, the corresponding text field in the target is also expanded.
- If the scale or the precision of a numeric field is modified in the source, the corresponding numeric field in the target is modified.
Note: If you add custom entities to your source data, or there are changes to source entities, reset metadata for the Connector to reflect those changes in TIBCO Cloud™ Integration - Connect. See Resetting Metadata.
