KnowledgeMan and GURU Introduce Improved User Interface, Faster
Performance, and Event-Driven Programming in Version 3.1

Lafayette, IN - January 8, 1993 - Micro Data Base Systems, Inc. (mdbs)
announces the release of version 3.1 for both KnowledgeMan and GURU.
KnowledgeMan is a relational database management system for business
applications. GURU is a comprehensive expert system environment.

Version 3.1 highlights include a completely rewritten user interface, I/O
speed improvements, and the addition of new event-handling functions to
the KGL programming language.

KnowledgeMan and GURU are both available for single-user MS-DOS based PCs,
OS/2, most popular LANs, DEC VAX/VMS, and SUN Unix environments

Micro Data Base Systems, Inc. (mdbs) announces version 3.1, the newest
release of KnowledgeMan and GURU.

Improved Commander Interface

Querying capabilities of Commander have been greatly improved. In this new
version, Query By Example (QBE) allows users to make multiple queries on
multiple tables and display the results on the screen in tabular form or
as a standard select listing (on screen or printer). The queries generated
by the QBE interface are optimized to take advantage of available indexes.
The code used to generate these views can be saved to a file for re-use or
to incorporate into an application.

The use of a mouse is now fully supported by Commander. In addition,
Windows and Presentation Manager-like file dialog and output redirection
boxes are now used throughout Commander, giving the interface a distinctly
GUI character.

I/O Speed Improvements 

The I/O speed of both screen and disk has been improved greatly in
KnowledgeMan and GURU version 3.1. The net gain in any application depends
on the nature of the application and whether it takes advantage of the
specific improved operations.

Event Handling

Eight new event handling functions have been added in KnowledgeMan and GURU
version 3.1 to give developers the low-level functionality needed to
create GUI-like event-driven applications. Sample source code illustrating
KGL event-driven programming is included in the 3.1 package.

Sales Information

The 3.1 update price for current GURU customers is $700. For current
KnowledgeMan users, the 3.1 update price is $450 and includes a full year
of service and maintenance. For more sales information, call (800) 344

Version 3.1 is available for single-user MS-DOS based PCs, OS/2, most
popular LAN's, DEC VAX/VMS and SUN Unix environments. Locking mechanisms
allow developers to create multi-user LAN applications across these
environments. Applications are portable across all operating environments.
KnowledgeMan and GURU are extensible through many 3GLs such as C and
FORTRAN.
