Assign a Data Type to a Domain

A data type is a domain property and defines the physical properties of a column in a database such as length (number of characters), type (alpha or numeric), and precision (decimal). You can also define a logical data type, which usually corresponds to a physical data type.

By default, a new domain is assigned the same data type as its parent domain. You can change it at any time. The available data types for the current model always appear in the drop-down selection in fields where the data type is defined in the Domain Editor.

To assign a data type to a domain

1. Click Domains on the Model menu.

   The Domain Editor opens.

2. Select the domain in the Navigation Grid for which you want to assign a data type. Use the Enter filter text box to filter a large list to quickly locate the domain.
3. Select a new data type for the domain using the drop-down list in the Logical Data Type column (logical edit mode) or the Physical Data Type column (physical edit mode) in the Navigation Grid.
4. Click Close.

   The data type is assigned to the domain and the Domain Editor closes.
