McDonnell Information Systems (MDIS) and Micro Data Base Systems, Inc.
(mdbs) to Form Business Relationship

Irvine, CA - December 17, 1993 - Micro Data Base Systems, Inc. (mdbs) and
McDonnell Information Systems (MDIS) announce intent to form a business
relationship allowing both companies to share technologies for the mutual
development of a database schema generator. Never before have a CASE
vendor and a database vendor united.

Two technical powerhouses, McDonnell Information Systems (MDIS) and Micro
Data Base Systems, Inc. (mdbs), have come together to create a powerful
tool using mdbs' database engine and MDIS' Pro-IV Workbench CASE tools and
fourth generation development language. The interface between MDIS' data
modeling tool, PRO-IV Workbench, and the mdbs database engine will allow
automatic database schema generation.

MDIS

MDIS, an international technology company with headquarters in the United
Kingdom, is a supplier of global solutions for open systems environments.
MDIS has a 22 year history with investment software applications and
hardware technology and boasts a comprehensive array of information
technology skills and experience.

PRO-IV Workbench

MDIS' PRO-IV Workbench is engineered to work naturally with the mdbs
data-Workbench base engine. PRO-IV Workbench is used to create a graphical
diagram of an application's entity-relationship data model. PRO-IV
Workbench then automatically creates an mdbs database schema that
implements the application's entity-relationship model directly in the
database. Exclusive features of PRO-IV Workbench include the following:

* Real-time work group data sharing in a multi-user LAN
  environment
* Rich graphic modeling with engineering-sized color plotted
  output
* Robust repository-based management and control of all project
  facts
* screen and report prototyping with life-like executable
  simulations of real systems
* Extensive standard reporting complemented by powerful and
  flexible ad hoc query and reporting of all project facts

Simplifying Complexity

By combining their 100+ years of experience in database, AI,
re-engineering, and Complexity CASE tools technology, mdbs and MDIS will
build tools for highly complex applications. The mdbs engine supports
complex data relationships directly in the database, including
many-to-many, forked, recursive, and other types of object relationships
not supported in traditional database systems. This direct support
produces efficient, high-performance applications that implement
real-world complex data models. PRO-IV workbench graphically depicts the
files used resulting in a schema having a high-level language specific to
a particular database.

mdbs database engine

mdbsMicro Data Base Systems, Inc. was founded in 1979 and is a world leader
of development tools for complex information management applications.
mdbs' client/engineserver database engine is used for critical database
applications involving complex data relationships.
