The DATATRIEVE Programmer

This page was created and is maintained by
Joe H. Gallagher
former Newsletter Editor and SIG Chair
of the
DATATRIEVE/4GL SIG of DECUS.

This web resource is dedicated to DATATRIEVE programmers, developers, and members of the DATATRIEVE and 4GL SIGs of DECUS who supported and promoted the DATATRIEVE programming language.





















What is DATATRIEVE?

DATATRIEVE has been described as a query language, report writer system; a fourth generation language; and a system for managing data. It is all of that and more.

The Software Product Description for Version 7.2 of DATATRIEVE in PDF format is on the Compaq server for Alpha and for VAX. The Software Product Description of DATATRIEVE-11 has been dropped from the Mentec Web site.

DATATRIEVE is now a "Mature Product." Mature Product status means that no new features or functionality are being developed. As such, Compaq no longer offers product updates or right to new versions. However, Compaq does offer full remedial support with engineering backup under Mature Product Support. The backup engineering support now comes from Nashua, NH out of the OpenVMS Sustaining Engineering group.

DATATRIEVE and FMS are the two Mature Products which are to be ported to the Itanium family of processors.

What DATATRIEVE resources are available on the Web?

The 5 major manuals of Version 6 of DATATRIEVE are at the Warsaw Agricultural University site in Poland. Currently, there are no Version 7.2 DATATRIEVE manuals available to users on the Internet. If manuals become available, they are likely to be accessible via Compaq's Commercial Software page. If anyone knows of or should find a set of Version 7.0 or Version 7.2 DATATRIEVE manuals available on the Internet, please let me know.

Western Michigan University has a two-part introduction to DATATRIEVE. Part 1. Part 2.

There are VAX-Notes Conferences on the ENCOMPASServe machine. Relevant notes streams have been reviewed and indexed for your convenience.

DATATRIEVE questions in news groups via Google Groups -- old stuff and recent stuff

Departmental Accounting with DTR, a presentation at the 1995 Fall Symposium by Paul Waterstraat, describes an interesting DATATRIEVE application.

Also on the web are hundreds of resumes of individuals who have programmed in DATATRIEVE and several hundred Compaq web sites with legal notices that DATATRIEVE is a trademark of Compaq(Digital Equipment Corporation).
