Transforms

A transform is a special formatting routine used for populating VIRTUAL data sets or transforming an update in other ways.

A transform is a user-written procedure that is used by the Support Library (similar to an INTERNAL FORMAT). A transform has access to both the before- and after-images at the same time.

The following transforms are predefined in the Support Library:

• ChangedRecordsOnly—Discards records if none of the data items allowed by the filter are modified.
• ChangedItemsOnly—Discards unmodified data items. The accessory receives only the key items and data items that changed. Note that this transform is not supported by the DATABridge Client.

Refer to the DATABridge Programmer’s Reference for instructions on creating transforms.
