Customer Information Control System (CICS) is introduced by IBM in 1960s to support online programming on Mainframes. CICS acts like a sub-operating system, it manages its own memory space, control the concurrent execution of multiple applications. CICS is it self is a batch job running on Mainframe to enable application programs to respond to online requests. You can see the CICS job running on mainframe, by checking in the spool. System operators daily run this CICS job. We can observe multiple instances of CICS jobs are running on mainframe.
- Acts as interface between operating system and application programs
. - Does the function of data communication and therefore handle data. In other words CICS can support number of terminals or systems and acts as a data communication system between them.
