How Model Selection Works

Select the models, script file, or database for the compare. Some of the typical compare scenarios you can use are:

• Compare your active data model open in the workspace with a model saved as an *.erwin file.
• Compare a data model with a script or database.
• Compare two databases or two scripts.
• Compare two unrelated models.

Click Complete Compare on the Actions menu. The Right Model Selection dialog opens by default.

You can work with models already open in the workplace, or you can use the Complete Compare Wizard to open a model, or reverse engineer a database or script file.

• Select from the “Load From” choices to open a new *.erwin file, or compare to a database or script file. When you select the Database/Script option, the Reverse Engineer dialog opens, which allows you select specific options. If you have a connection to a mart, you can open a model from a library.
• Move the focus in the Open Models in Memory list to choose a model already open in the workspace.

To navigate the panes of the Complete Compare Wizard, click the name of the pane in the static explorer area in the wizard to display that pane.

Since the wizard is non-sequential, you can select as many or as few options as you want, and start the compare process at any time.

After you select the Right Model, click Left Model in the navigation pane to open the Left Model Selection dialog. Select a model, database, or script file for the "Left Model" in the compare.

Note: You can use the preset defaults for all the other options in the Complete Compare Wizard. To accept the defaults and start the compare process, click the Compare button after you select the right and left models.
