Creating a Resource Based on a DTD

To create a resource based on a DTD:

1. Display the File Explorer.
2. Find the DTD on which you want to base the resource. Select it, and drag and drop it in the application.

   The Workbench displays a popup menu with the options Query and Update.

3. Select the type of resource you want to create.

   Percussion adds the resource to the application.

4. To modify the resource, double-click on it. The Workbench opens the resource in a separate tab.

A query resource created from a DTD includes a Page Data Tank, Mapper, and Selector on the Data Pipe. You must add at least one database table to add a Backend Data Tank. The Mapper does not include any mappings and the Selector does not include selection criteria. You must add mappings and selection criteria. (Note: You can only add mappings and selection criteria after you have added a Backend Data Tank with at least one table.)

An update resource created from a DTD includes a Mapper and Updater. You must add at least one database table to add a Backend Data Tank. The Mapper does not include any mappings, so you must add them; you can only add mappings if you have added a Backend Data Tank with at least one table.
