CA Datacom/DB Reporting Facility

The Reporting Facility is an easy-to-use file retrieval and report generating system. Communication with the system is through the Reporting Facility language. This language is made up of simple English-like input statements used to access a database and establish the contents and format of the report.

You must code these statements in a prescribed manner and then submit them with the appropriate Job Control Language (JCL) statements. Some of the statements direct the program to access specified data from the database.The Reporting Facility reads the statements and produces the desired report. For the JCL statements required to execute the program under z/OS and z/VS, see Sample Reporting Facility JCL Streams.

The generalized interactions between the input statements, the system, the database, and the final report are illustrated below:
