October 5, 1997 — New York, NY. — DAS Works, maker of ListTable(TM),
announces the release and shipment of Jovis(R) Version 1.0.4, an XCmd
database engine, and the only fully scriptable database engine available
for the Macintosh. It allows users to create single-user, and/or
client/server applications with any scriptable application such as
HyperCard, SuperCard, Oracle Media Objects, Frontier, and others. With
Jovis, data is kept in database files external to the application. The
application’s scripts include Jovis “calls” that manage and update these

“Jovis is the best HyperCard/SuperCard-oriented database
engine available today. It provides a fast and powerful
solution where one is sorely needed.”

-Jeff Benjamin, StepUp Software, Inc.

Because Jovis was designed and created as an extension to scripting
environmen ts (not “spun-off” from a database management system or any
product that requires expert knowledge of SQL), it is easy to learn and
simple to use.

Jovis provides over 175 Relational and Architectural commands. The
Relational commands provide all of the standard features and performance
requirements expected in a relational database system. The Architectural
commands, (commonly referred to as “Flat File” commands) include many
enhancements and capabilities, making them far more useful and beneficial
than ordinary file utility commands.

“We use the Client/Server version of Jovis as part of our
multimedia clinical information system. I am impressed
with Jovis’ performance and versatility. It is a wonderful
system for rapid database prototyping. The developer
technical support is excellent.”

-Henry Lowe M.D.
-Director, Clinical Multimedia Laboratory
-University of Pittsburgh Center for
Biomedical Informatics

With Jovis, developers can store and retrieve text as blocks of data, or as
records using relational tables. Additionally, they can store and retrieve
‘Pict’s, ‘snd ‘, and ‘Blob’s (Binary Large OBjects). Developers have the
ease of use that comes with variable field and record lengths as well as
concurrent multiple selections. Most importantly, Jovis gives developers
the ability to keep their data separate from their application’s interface.

A Jovis datafile can contain virtually unlimited amounts and types of data.
Users can store hundreds of thousands of records in a single data file, or
in multiple open data files, limited only by hardware sonstrants.

Jovis Server uses classic AppleTalk and System 7.1 or greater. It can reach
across zones and allow access from any location on a network. No other file
servers or network software is required.

The comprehensive printed manual provides everything necessary for both
learning and using Jovis. There are 16 tutorials, 3 syntax reference
sections, and extensive appendices.
