Reverse Engineering from Scripts

PowerDesigner can reverse engineer a PDM for one or more SQL script files.

Note:

When working with the PowerDesigner Eclipse plug-in you can, in addition to the procedure below, select any SQL file in the Navigator, right-click it and select Reverse Engineer from SQL File. You will be given the option to reverse into an existing or new PDM.

To reverse engineer a script into an existing PDM, select Database > Update Model from Database .
or

To reverse engineer a script and create a new PDM, select File > Reverse Engineer > Database to open the New Physical Data Model dialog box. Specify a model name, choose a DBMS from the list, and then click OK.
When the Database Reverse Engineering Options dialog box opens, click the Using script files radio button.
Note:
You can add as many script files as necessary to the list. The reverse engineering process handles files sequentially. Trigger scripts must always be executed after table scripts. This is the only constraint for ordering your files in the list, but it is essential for a successful reverse engineering of triggers. Use the Move tools to position the files correctly in the list.
Click the Options tab to specify any reverse engineering options. For more details, see Reverse engineering Options tab.
Click the Target Models tab to specify any external shortcuts. For more details, see Reverse engineering Target Models tab.
Click OK to begin the process of reverse engineering. When the process is complete, a confirmation message is given in the Output window. If you are reverse engineering to an existing PDM, then the Merge Models dialog box opens to help you merge the new objects into your PDM.
