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.
A database-utility program would use the database description file to create the remaining components of the database. Proprietary language compilers (such as COBOL and ALGOL) would use the database description file to create database-related elements in the object code of the compiled program. These compilers used language extensions to ...
TELON is an application development system currently sold and maintained by CA Technologies (formerly CA, Inc. and Computer Associates International, Inc.). When it was introduced in 1981, it was one of the first computer-aided software engineering ("CASE") tools on the commercial market.
IBM Db2 Community Edition is a free-to-download, free-to-use edition of the IBM Db2 database, which has both XML database and relational database management system features. Version 11.5 provides all core capabilities of Db2 but is limited to 4 virtual processor cores, 16 GB of instance memory, has no enterprise-level support, and no fix packs ...
This stub has entry points to handle a variety of programming languages, e.g., calling CBLTDLI from a COBOL program. 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.
Adabas, a contraction of "adaptable database system", [1] is a database package that was developed by Software AG to run on IBM mainframes. It was launched in 1971 as a non-relational [2] database. As of 2019, Adabas is marketed [3] for use on a wider range of platforms, including Linux, Unix, and Windows. [4]
The Integrated Database Management System (IDMS) is a network model database management system for mainframes. It was first developed at B.F. Goodrich and later marketed by Cullinane Database Systems (renamed Cullinet in 1983).
Non-Shared Resources (NSR), which is optimised for sequential access. NSR access has historically been easier to use than LSR for batch programs. [12] Distributed File Management (DFM), an implementation of a Distributed Data Management Architecture server, enables programs on remote computers to create, manage, and access VSAM files.
