Learn CICS from best Institutes in Mumbai. CICS or Customer Information Control System is an online transaction processing (OLTP) program from IBM. Together with the COBOL programming language, it has formed the most common set of tools for building customer transaction applications in the world of large enterprise mainframe computing over the past several decades. A great number of the legacy applications still in use are COBOL/CICS applications. Using the application programming interface (API) provided by CICS, a programmer can write programs that communicate with online users and read from or write to customer and other records in a database which is usually referred to as data sets using CICS facilities rather than IBMs access methods directly. CICS can ensure that transactions are completed and, if not, undo partly completed transactions so that the integrity of data records is maintained just like other transaction managers.

CICS is a data communication system that can support a network containing hundreds of terminals. CICS manages the sharing of resources, the integrity of data and prioritization of execution, with fast response. CICS authorizes users, allocates resources (real storage and cycles), and passes on database requests by the application to the appropriate database manager (such as DB2). We could say that CICS acts like, and performs many of the same functions as the z/OS operating system.

A CICS application is a collection of related programs that together perform a business operation, such as processing a travel request or preparing a company payroll. CICS applications execute under CICS control, using CICS services and interfaces to access programs and files. CICS applications are traditionally run by submitting a transaction request. Execution of the transaction consists of running one or more application programs that implement the required function. In CICS documentation you may find CICS application programs sometimes simply called programs, and sometimes the term transaction is used to imply the processing done by the application programs. CICS applications can also take the form of Enterprise Java Beans. You can find out more about this form of programming in the section on Java applications in CICS in the CICS Information Center..
