System Table TB_JOB_PERIMETER

The system table TB_JOB_PERIMETER administers the job perimeters.

Attributes of TB_JOB_PERIMETER	Description
JOB_ID	Specifies the job the perimeter belongs to (TB_JOB).
JOB_PERIMETER_TYPE_ID	Specifies the perimeter type. Type 1—Stores the perimeter that has been digitized or selected. For type 1 perimeters no F_CLASS_ID is stored. Type 2—For each perimeter feature class that is used in the job template, one type = 2 perimeter is created.
F_CLASS_ID	Specifies the ID of the perimeter feature class.
TOPO_ID	Specifies the ID (TB_TOPOLOGY.ID) of the topology that builds the geometry of the perimeter. For JOB_PERIMETER_TYPE_ID=1 perimeters no TOPO_ID is stored.

Example: The job template contains the topics Parcel and Land Cover. Each topic is part of a topology and has its own perimeter feature class. In a job, when you select the perimeter using the parcel topology, an intersection with the land cover topology is performed and for each perimeter feature class a record with JOB_PERIMETER_TYPE_ID=2 and the TOPO_ID is added.
