Work Areas

Work Areas contain object instances, each of which points to an object definition located either in an Application Area or in a Library. This diagram shows only object ownership, so you cannot see the pointers to the definitions. Most object instances point to an object definition with the same type name; for example, Program instances point to Program definitions. There are two exceptions: both a Parameter and a Table Column point to a Variable as their definition source.

Figure B-3 shows all possible layers of object ownership within a Work Area. The objects are Program Instances, Load Set Instances, Report Set Instances, Data Mart Instances, Work Flow Instances, each of which contain the following objects:

• Table Descriptor to Table Instance mapping

• Execution Setups. These contain Parameter Set Instances containing Parameter Instances, and Jobs containing Outputs.

In addition, Work Areas also contain:

• Table Instances that contain Constraints

• Business Area Instances that contain Table Descriptor to Table Instance mappings
