Deriving from Base Type Elements

When modeling simple and structured data elements in Design Studio, you can create new data elements that derive from existing base types. Rather than referencing one of the primitive types (int, boolean, char, and so forth), you reference another data element as their data type.

To create data elements that derive from existing base types:

1. From the Studio menu, select Show Design Perspective.

2. Click the Dictionary tab.

3. Right-click in the Dictionary view area and select the appropriate menu option.

   • To create a data element that will contain no child elements, select Add Simple Schema Element.

   • To create a data element that will contain child elements, select Add Structured Schema Element.

4. In the Type field, click Select.

   The Data Element Selection dialog box appears.

5. Select an existing data element as the base type for the new element.

   The new element becomes a subtype of the element you select here, and inherits some of the base type element attributes.

6. Enter information for all required fields.

   See "Creating New Simple and Structured Data Elements" for more information.
