Trinzic InfoHub For Micro Decisionware Database Gateway Now Available

Joint Solution Provides Direct SQL Access to Non-Relational Mainframe Data

Chicago, IL, at Database World, December 8, 1993--Trinzic Corporation
(NASDAQ:TRNZ) and Micro Decisionware Inc. (MDI) today announced the
general availability of the new InfoHub client/server software product for
the MDI Database Gateway. The combination of these two powerful products
constitute the industry's most flexible, high performing enterprise data
access solution, enabling direct SQL access to the 80 percent of corporate
data that is stored in non-relational, legacy systems.

For the first time users can directly read, write, update and join all
mainframe data including CA/IDMS, IMS, VSAM, Adabas, DB/2 and sequential
files from the many popular front-end application tools written to the
Open Database Connectivity (ODBC) Application Programming Interface. This
can be done without the need for mainframe programming.

"Micro Decisionware's and Trinzic's support of ODBC is an important element
of our strategy to facilitate the implementation of client-server
applications in large organizations," said Jonathan Lazarus, Vice
President of Systems Strategy at Microsoft Corporation. "It's important to
customers because it enables them to choose the application tools and
DBMSs best suited to their business needs."

Beta Tests Demonstrate Ease-of-Use and Versatility Meeting Customer Needs

Minnesota Power participated in the customer testing program for InfoHub
with Database Gateway. "InfoHub allows the mainframe to look like a local
server database," commented Jerry Hauge, Database Administrator with
Minnesota Power. "It will allow our Windows development tools to access
ADABASE and create applications faster than writing mainframe code. In
addition, our applications will be transportable so that we can eventually
migrate mainframe data onto SQL Server or some other DBMS without our
users being affected."

InfoHub for MDI's Database Gateway was also successfully beta tested at
many customer sites including the Provincial Government of Alberta, Canada
and Southern California Gas.

The Trinzic/MDI Partnership is a Winning Combination for Customers

The Trinzic/MDI partnership was announced in June of this year at the
Database World. Under the terms of the agreement, MDI is marketing
Trinzic's InfoHub and InfoPump data management tools with its Database
Gateway product line. "InfoHub provides what no other product has
delivered--ad hoc access and update capability, automatic generation of
all DBMS specific code and support for advanced relational features like
triggers and stored procedures," said Frederick J. Lizza, Trinzic's vice
president and general manager of data access and connectivity products.
"This cooperative partnership opens up a vast array of access to users
needing access to non-relational data. MDI's sophisticated access from the
network and Trinzic's technology is a powerful combination. "

Quick and Easy Access to Time-Critical Data Without Mainframe Coding

MDI President Michael H. Forster echoed Lizza's comments saying, "This
joint solution makes our customers the clear winners by enhancing their
access to large stores of nonrelational enterprise data which is so
critical to their decision support and application development processes.
" Until now access to non-relational data has been accomplished largely
through the use of the remote stored procedures (RSPs) capabilities of the
Database Gateway. While RSP's are an excellent method for executing
routine database queries, the combination of Database Gateway and InfoHub
provides customers with the ad hoc access they want. It also enables them
to join non-relational data with all the ease of use afforded by their
front-end tools such as Trinzic's Forest & Trees, PowerBuilder and Visual
Basic.
