DBMS Definition Files

A DBMS definition file is a PowerDesigner resource file that provides PowerDesigner with the information necessary to model, reverse-engineer, and generate a particular DBMS.

PowerDesigner provides definition files for most popular DBMSs. The DBMS definition files are located in install_dir/Resource Files/DBMS, and have an .xdb extension.

Note: Modifications to a DBMS definition file can change the way PowerDesigner functions work, especially when generating scripts. Make sure you create backup copies of your database and thoroughly test generated scripts before executing them.
