Physical Attributes of TOU Map vs. Its Role

You will see, as you learn more about the design of TOU mapping, that there are two control tables that are important for defining TOU maps:

• TOU Map Type - this defines the physical attributes of the TOU Map
• TOU Map Relationship Type - this is needed for TOU maps that are linked to a service agreement. It defines the role that the TOU Map is playing for that service agreement. You can also think of this as defining the business purpose of the data.
