IBM's Customer Information Control System (CICS) is the leading product family in the on-line transaction processing (OLTP) market. OLTP systems are being used by many enterprises to implement their daily business processes and manage operational data such as accounts, inventories, and orders. CICS/Distributed Data Management (CICS/DDM) implements the distributed file function of Systems Application Architecture® (SAA™) Common Communications Support in the CICS environment on Multiple Virtual Storage (MVS) and Virtual Storage Extended (VSE) operating systems. Providing a DDM target server, CICS/DDM implements IBM's SAA protocol for access to distributed data, which are exploited by the SAA Common Programming Interface. CICS/DDM allows applications and their users to access and share the data managed through the OLTP environment provided by CICS.
