Chapter 12 DBMS-Specific Features

Working with PowerDesigner's DBMS-Specific Features

This chapter provides information about the DBMS-specific features in PowerDesigner.

PowerDesigner provides customized support for a wide range of database families through DBMS-specific resource files. These files have a .xdb extension, and are located in the "Resource Files\DBMS" directory inside your PowerDesigner installation directory.

Resource files support, among others, three kinds of customization for PowerDesigner model objects:

• Assignment of standard objects to the specific syntax of a DBMS
• Definition of Extended Attributes for certain objects to allow for DBMS-specific object properties
• Definition of additional DBMS-specific model objects.

You can view and edit the resource file for your selected DBMS in the Resource Editor by selecting Database→Edit Current DBMS.

For more information about working with resource files and the Resource File Editor, see the following chapters in the Customizing and Extending PowerDesigner manual:

• Resource Files and the Public Metamodel
• DBMS Resource File Reference
• Extending your models with Profiles
