Create an XDD Manually

If you do not have access to an external file definition such as an XFD (COBOL), a DDF (Btrieve), your Btrieve program source code, or create an XDD manually with an editor.

Users of c-treeRTG BTRV Edition who do not have a DDF can use these procedures if they desire SQL access to their data.

The XDD file can be created using any XML editor.

To manually create an XDD, you need to know the structure of your data. You then need to translate that structure into an XDD. The XDD is explained in the section titled XDD Schema Structure.

After creating the XDD, use the procedures in the section titled SQLIZE: Persist XDD to Data File and Link to SQL Dictionary to prepare data files for SQL access.
