Chapter 6 Managing Models
Resource Files
The PowerDesigner modeling environment is powered by resource files, which define the objects available in each model along with the methods for generating and reverse-engineering them. You can view, copy, and edit these XML-format resource files in order to customize and extend the behavior of the environment. The following types of resource files are provided:
- Target languages: define the standard objects available in a model. Types of target language files include:
- Process languages (.xpl) – define a specific business process language in the BPM (see the "Process Language Reference Guide" chapter in the Advanced User Documentation
).
- Object languages (.xol) - define a specific object-oriented language in the OOM (see the "Object Language Reference Guide" chapter in the Advanced User Documentation
).
- DBMSs (.xdb) - define a specific DBMS in the PDM (see the "DBMS Reference Guide" chapter in the Advanced User Documentation
).
- XML languages (.xsl) - define a specific XML language definition in the XSM (see the "XML Language Reference Guide" chapter in the Advanced User Documentation
).
- Extended model definitions (.xem) – extend the standard definitions of target languages to, for example, specify a persistence framework or server in an OOM. You can create or attach one or more XEMs to a model (see the "Extended Model Definitions Reference Guide" chapter in the Advanced User Documentation
).
- Report templates (.rtp) - specify the structure of a report. Editable within the Report Template Editor (see the Reports User's Guide
).
- Report language files (.xrl) – translate the headings and other standard text in a report (see the Reports User's Guide
).
- Conversion tables (.csv) - define conversions between the name and code of an object (see "Using a conversion table" in the "Managing Models" chapter).
