This diagram shows that Oracle LSH can pull data into the same Work Area from an external system, which requires a Load Set, and from another Oracle LSH Work Area, which requires a Program instance's source Table Descriptors to be mapped to a Table instance in the other Work Area. The Program instance and the Load Set instance each write data to a different Table instance. It is then possible to combine the data into a single Table instance using another Program instance, and to report the data via another Program instance.
