The IBM Information Management System (IMS) is a joint hierarchical database and information management system that supports transaction processing. [1] Development began in 1966 to keep track of the bill of materials for the Saturn V rocket of the Apollo program, and the first version on the IBM System/360 Model 65 was completed in 1967 as ICS/DL/I and officially installed in August 1968.
This stub is linked to the calling program, passes on the request to the IMS system, and returns the results and a status code. In any full-function IMS database, the smallest element that can be retrieved is a segment. Each segment is made up of fields, one of which, typically, will be a key field. The segments are arranged hierarchically in ...
A number of intrinsic functions were inserted by the compiler to ensure the program and database used the same definition of database structures. Originally, DMSII maintained a data dictionary that the application programmer referenced in its source code. The source for the data structures was maintained in an ordinary CANDE source file. That ...
DB2 pureScale is a cluster database for non-mainframe platforms, suitable for online transaction processing (OLTP) workloads. IBM based the design of DB2 pureScale on the Parallel Sysplex implementation of DB2 data sharing on the mainframe. DB2 pureScale provides a fault-tolerant architecture and shared-disk storage.

Custom programs can access VSAM datasets through Data Definition (DD) statements in Job Control Language (JCL), via dynamic allocation or in online regions such as in Customer Information Control System (CICS). Both IMS/DB [citation needed] and Db2 [2]: 41 [6] are implemented on top of VSAM and use its underlying data structures.
CICS supports XA two-phase commit between data stores and so transactions that spanned MQ, VSAM/RLS and Db2, for example, are possible with ACID properties. CICS supports distributed transactions using SNA LU6.2 protocol between the address spaces which can be running on the same or different clusters.
TELON supported multiple database technologies, including IBM's VSAM, IMS/DB, DB2, plus Cullinet's IDMS. TELON is an application code generator that uses macros to generate COBOL , COBOL/II , or PL/I code that can run natively in the target environment without run-time proprietary code.
