These classes have different prefixes depending on their functionality. The following table explains the meaning of the prefixes.

| oa | Classes with the oa prefix, such as oaChangeMgr and oaChangeRec, are classes that support the basic CMS capabilities. Specifically, oaChangeMgr provides functions to manage the CMS plug-ins, oaChangeRec and its derived classes allow for the creation of objects that capture information about changes to design data., and oaChangeSet provides a mechanism to group oaChangeRec objects. |

| sd | The sd or schema definition classes provide metadata for the OpenAccess information model. The schema definitions are used to define the objects, attributes, relationships, and values for OpenAccess managed objects. For example, an sdObject can provide the generic schema definition for any OpenAccess class by specifying the attributes and relationships that can exist for objects of that class. |
sdBase srBase Creating Schema Definitions |
| sr | This is the abstract base class to represent an attribute. It contains a pointer to the sdAttribute that defines the schema definition for the representation and an srObjectRef pointer to store the object from which the attribute value was obtained. The derived class will need to specialize for the specific value type. |
