The following sections provide more detailed schema diagrams for the individual Things. In these detailed schema diagrams, the <database_object_name>_AP tables in each schema diagram are for additional properties (AP). When Operator Advisor is initially installed, these tables are empty. For each specific implementation, more properties can be added to these tables. Some general ThingWorx services are provided to create, delete, and query these additional properties. The out-of-the-box upgrade process does not touch these tables.

For more information on using the <database_object_name>_AP tables, see Adding Custom Properties to Operator Advisor Entities.
