Set Data Type Options for the Current Model

If you use data type standards, you must attach a data type standards model file to each model that you create. If you do not attach a data type standards model file to a model, the default logical data types and data type mapping are used. You can use the Model Data Type Options dialog to select a data type standards model file (*.dsm) that you want to attach to the current model, and to open the Data Type Standards Editor.

To set data type options for the current model

1. Click Model Data Type Options on the Actions menu.

   The Model Data Type Options dialog opens.

   Use File

   Use ERwin MM File

   Specifies to use an existing data type standards model file that is stored in a mart library and attach it to the current model. Click Browse to locate the file that you want to use. The Last Updated field displays the date and time the data type standards model file was last updated.

   Edit

   Specifies to use the Data Type Standards Editor to view and make any changes necessary to the data type standards model file that you just attached.
