8.3. Create a New Relational View Model


8.3.1. Create a New Relational View Model

To create a new empty relational view model:
  1. Launch the New Model Wizard.
  2. Specify a unique model name.
  3. Select Relational option from Model Class drop-down menu.
  4. Select View Model from Model Type drop-down menu.
  5. Click Finish.

Note

You can change the target location (i.e. project or folder) by selecting the Browse... button and selecting a project or folder within your workspace.
In addition to creating a new empty relational view model, the following builder options are available:
  1. Copy from existing model of the same model class.
  2. Transform from existing model.

8.3.2. Copy an Existing Relational View Model

This builder option performs a structural copy of the contents of an existing model to a newly defined model. You can choose a full copy or select individual model components for copy.
To create a new relational model by copying contents from another relational view model, complete first 4 steps from the Create a New Relational View Model section and continue with these additional steps:
  1. Select the model builder labeled Copy from existing model of the same model class and click Next >. The Copy Existing Model dialog will be displayed.
  2. Select an existing relational model from the workspace using the browse button.
  3. Select the Copy all descriptions option if desired. Click Finish.

8.3.3. Transform from an Existing Relational View Model

This option is only applicable for creating a relational view model from a relational source model with the added feature of creating default transformations (SELECT * FROM SourceModel.Table_X) for each source table. The steps are the same as for the Copy from Relational View Model section described above.
There is an additional option in the second dialog window of the wizard which can automatically set the relational table's supports update property to false. If this is not selected, the default value will be true.
