Gembase Platform

Gembase was originally developed by a U.K. company called Pioneer. For reliability, they chose to develop Gembase on Digital’s VAX/VMS platform, and using the Digital RDB database engine. Gembase was developed as the successor to their older product, USERBASE.

Now, Gembase is provided by Ross Systems Inc. Ross have taken Gembase from its limited market, and made Gembase a more open product. Ross are among the largest users of Gembase, having developed their Renaissance CS product range in Gembase. (Renaissance CS, frequently shortened to RenCS, is an E.R.P. - Enterprise Resource Planning - package). So, as users of Gembase, Ross have had an interest in making it available on as many platforms as possible - this allows their other products to also have a wider market.
The Gembase Data Dictionary provides the developer a method of controlling and configuring the underlying database, without learning a new set of tools and commands when the database engine changes. Since most database engines work through SQL, the interface to the underlying database engine has a high-level consistency. Provided the Data Dictionary interface and commands remain consistent, the underlying interface can be tuned to take advantage of features of each database engine.
