Object Hierarchy
The objects that OLE DB Provider for Teradata exposes to the consumer are organized in a parent-child hierarchy. First, create the parent object, then create the child object. Use the COM facilities to create the highest-level object, Data Source. Starting from the Data Source object, each object has a built-in factory to create child objects. The following diagram shows the hierarchy of some of these objects:
