Creating a Derived Class
A derived class lets you create a logical class using properties that exist in already defined classes. Derived class objects look like normal class objects to the APIs. However, only the class definitions for a derived class are stored—there are no physical objects in a derived class. For more information on derived classes and the advantages of using them, see “Derived Classes” on page 74.
To create a new derived class for a specific AIM:
1 In the Meta Data Services Navigation Pane, click Metamodel Administration.
2 From the Repository Metamodels drop-down list, select the metamodel name, and then click Go.
3 Click the radio button next to the base class in the Classes and Relationships area, and then click Derived Class.
The Create Derived Class screen appears.
The Base Class field displays the base class selected to derive the new class. This box is read only.
4 Enter or select the necessary information.
For detailed instructions, click 
.
5 Click Create.
Upon successful completion, the right pane displays the MDS Metamodel Administration screen for the current metamodel. The new derived class appears in the Classes and Relationships area.
