Runtime Interface

The runtime interface:

Accepts retrieval and update requests from the DL/I application programs
The interface then processes the requests into appropriate CA IDMS/DB requests and sends them to CA IDMS/DB
After CA IDMS/DB processes the requests, the runtime interface accepts the retrieved data and status information from CA IDMS/DB for placement in a format acceptable to the DL/I application program
To accomplish these functions, the runtime interface consists of special-purpose components, a front end, and a back end.

The special-purpose components, the front end, and the back end are discussed in the remainder of this appendix.
