An implementer could use VSAM
files as much as they want; however, they are asked to hide those VSAM
files from the data user's coding essentials if they wish to refer to their tool as "relational." Relational theory seems to be held to a higher standard by some; ballistics theory is not often held accountable for vendors providing bad cannons.
In addition, the introduction of VSAM
file encryption for z/OS enables customers to protect sensitive data on the mainframe.
For example the Defense Advanced Research Projection Agency (DARPA) supported the Visual Surveillance and Monitoring (VSAM
) project  in 1997, whose purpose was to develop automatic video understanding technologies that enable a single human operator to monitor behaviors over complex areas such as battlefields and civilian scenes.
The primary tools used on mainframe systems are still COBOL, DB2, CICS and VSAM
. In addition, numerous tools geared towards quality assurance exist as well.
The three-year Video Surveillance and Monitoring (Vsam
) programme began in 1997 was intended to develop state-of-the-art algorithms for automated video surveillance systems suitable for use in future urban and battlefield surveillance applications.

Bill Yeager, PDM's author and principal architect at Alebra's Atlanta development and support center, states that "the increased functionality provided by this release is exciting and significant, including MVS-MVS data transfer, efficient block movement, the ability to execute processes, programs and jobs on other nodes and get the results back to the source, symbol substitution, a new easier-to-use client interface, enhanced support for VSAM
and PDS, and automatic restart."
Commenting on the recent IBM announcement of the new Enterprise Storage Server, model 800 and 800 Turbo, disk storage system for z/OS, UNIX, Linux and Windows environments, independent storage management software vendor, INNOVATION Data Processing, Inc., assured customers that all components of its FDRINSTANT non-disruptive z/OS storage management solution, FDR/UPSTREAM its enterprise storage management solution for UNIX, Linux and Windows, IAM its VSAM
application accelerator and FDRPAS, its solution for the non-disruptive installation of new storage hardware and real-time data migration, are already shipping with full support for the new technology SHARK systems.
Some history is in order: The IT shop probably started life on the mainframe, using esoteric formats and languages such as VSAM
(Virtual Storage Access Method), QSAM (Queued Sequential Access Method) and COBOL (Common Business Oriented Language).
A continuous auditing solution must enable auditors to quickly access and retrieve data residing in any enterprise computing platforms, such as SAP R/3, Baan, PeopleSoft, Oracle, or SQL, as well as in various file formats, such as IMS, VSAM
, ASCII, MDB, CSV, XLS, TXT, used by business groups.
Evoke software's ability to profile virtually any existing data, including legacy IMS and VSAM
data is a significant capability requirement for Fortune 500 companies served by Evoke.
Evolutionary Technologies International's new ETI*EXTRACT 4.1 offers the ability to automate the generation and maintenance of interfaces to legacy systems such as IMS and COBOL VSAM
, and generate code that interfaces to message systems such as IBM's MQSeries, for the near real-time data exchange between applications required to support e-customers.
