Import from a Previous Version

If you have created naming standards for a previous version of CA ERwin DM, you can import them to an NSM Option object. You import a .NSM file.

Follow these steps:

1. Expand the Model Explorer, right-click NSM Options and click New.

   A new NSM Option object is added.

2. Right-click the new object (or an existing object) and click Properties.

   NSM Option Editor appears.

3. Click Import Other.
4. Select the .NSM file and then click Open.

   The NSM file is displayed as a new NSM Option object. The standards for Logical and Physical models are displayed in the respective tabs. The glossary words and corresponding abbreviations are displayed in the Glossary tab.

Upgrade Models with NSM or DSM Files

Suppose that the Source Mart version is prior to release 9.0 and it includes NSM or DSM files. When you upgrade the models, the naming and data type standards are not included in the upgraded model. The scenario applies to non-mart models as well. The reason for which the naming and data type standards are not included is, from release 9.0 onward Naming Standards and Data Type Standards are ERwin objects. These objects are now saved as part of a model under Naming Standards and Datatype Standards. The objects cannot be stored in a Mart or on the local computer.

Follow these steps:

1. Save the NSM and DSM files to your local computer, before you start the upgrade process.
2. Upgrade the models.
3. Create a model and import the NSM and DSM files that you have saved to your local computer. Save the model as a template model.

   We recommend that you do not include any other objects in this template.

4. Add naming and data type standards in one of the following ways:
   1. Attach a template model when you open the upgraded model for the first time:
      • Open the upgraded model.

        A message appears informing that you can either attach the default naming and/or data type standards or select a template model that has naming and/or data type standards.

      • Click No. Select the template model that you have created in Step 3.

        The naming and data type standards are imported to the model.

      • Click File, Model Templates, Synchronize on Model Load and save the model.

        This setting helps the target model synchronize with the template model when the template model is changed. The synchronization occurs whenever the target model is opened.

   2. Attach a template model after you open the upgraded model (using Active Model Template):
      • Open an upgraded model. Click File, Model Templates, Bind Template and select the template model that includes the NSM and DSM objects.
      • Select the Run the Template Wizard to select objects for synchronization and click OK.

        The Model Template Synchronization Wizard appears.

      • Click Model, select the Name_Mapping properties, and then click Ignore.

        This setting causes the name mapping properties to be ignored at the time of synchronization. This is because the Use Glossary options are not selected in the template model, but are selected in the target model. If you do not ignore the name mapping options, the name mapping options selected in the template are considered.

      • Click Actions, Model Naming Options. Go to the Name Mapping tab and ensure that the Use Glossary check box for the required object types are selected.
      • Click File, Model Templates, Synchronize on Model Load and save the model.

        This setting helps the target model synchronize with the template model when the template model is changed. The synchronization occurs whenever the target model is opened.
