Reinforcing DB2 Mappings with Extended Attributes

The IBM DB2 DAD extended model definition allows you to modify or reinforce the mapping resulting from the XML Builder Wizard via extended attributes.

Select Model > Extended Model Definitions, and click the Import tool.
Click the XML in Database tab, select the IBM DB2 DAD xem, and click OK to attach it to your model.
Click OK to close the List of Extended Model Definitions and return to your model.
[optional] Click the Preview tab of the Root element property sheet, and select the DB2XMLExtender.DAD File tab to preview the DAD file. If the DAD File tab is not available, click the Select Generation Targets tool to select IBM DB2 DAD in the Targets list and click OK.

Note:

You can also attach an XEM at model creation time by clicking the Select Extensions button on the New Model dialog.
