A Short Introduction to CICS
Short for Customer Information Control System, a TP monitor from IBM that was originally developed to provide transaction processing for IBM mainframes. It controls the interaction between applications and users and lets programmers develop screen displays without detailed knowledge of the terminals being used.
CICS, Customer Information Control System, is the premier OLTP (On-Line Transaction Processing) product family from IBM. CICS (pronounced "KIX" or "KICKS" by many, including the IBM CICS developers in Hursley, England) is sometimes referred to as a DB/DC (Data Base/Data Communication) system and recently celebrated its 35th birthday. With over 30,000 CICS licenses in over 20,000 businesses, CICS offers solutions to many businesses to solve complicated computing problems and offers many employment opportunities to CICS knowledgeable professionals. Over 90% of the fortune 500 companies run CICS.
Typical CICS applications include bank ATM transaction processing, library applications, student registration, airline reservations, etc.
The original design intent of CICS was to support a varied and large number of terminals and a large transaction volume with fast and consistent response time. CICS has occasionally been referred to as an operating system within an operating system, because it has a dispatcher, storage control, task control, file control, etc. It was designed to allow application programmers to devote their time and effort to the application solution, instead of dwelling on difficult technical issues. CICS can be described as an interface between the CICS applications and the operating system.
