CICS (Customer Information Control System) is a transaction server that runs primarily on IBM mainframe systems under z/OS or z/VSE. CICS is available for other operating systems, notably i5/OS, OS/2, and as the closely related IBM TXSeries software on AIX, Windows, and Linux, among others. The z/OS implementation is by far the most popular and significant.

A general purpose IBM mainframe-based transaction management system. CICS is one of IBM's most widely used database / data communications subsystems.

CICS is a transaction processing system (like TCAM) designed for both online and batch activity. On large IBM zSeries and System z9 servers, CICS easily supports thousands of transactions per second, making it a mainstay of enterprise computing. CICS applications can be written in numerous programming languages, including COBOL, PL/I, C, C++, IBM Basic Assembly Language, REXX, and Java.

The quality of the article is not up to the mark.It starts and ends abruptly, without giving clear picture about,what CICS is...And,it lacks explanation about the practicality and real time implementation.It is just brief and superficial and really a great disappointment to those who seek depth in it.

I cannot understand why this article was written - it does not give a good explaination of CICS. Where are the related topics?? I agree with deepa - it is very superficial.
