Many large organizations today still store gigabytes of mission-critical data in VSAM data sets on platforms such as z/OS and BS2000/OSD. Often, these environments will have a variety of software applications (often built in-house or custom made) that access and manipulate the data in these files through different VSAM Data Access Techniques. Frequently, these VSAM-based applications are written in the COBOL programming language.

To help organizations with large amounts of data, database vendors like Microsoft, IBM and Oracle have invested huge sums of money in the development of database management systems. These products serve as a "layer" or platform that aid organizations in the better and easier management of their data. Generally branded as an RDBMS (Relational DataBase Management System), these products take the concept of "data storage and access" and package it with advanced functionality. But despite these numerous attempts to replace relational databases with these new tools, they are still the working horse of all major corporations.
