Valentina Product Line to Support Purity Software's WebSiphon Development Tool

November 23, 1999. Beaverton, Oregon -- Paradigma Software and Purity
Software announced today a strategic development agreement that will result
in the release of a Valentina database solution for WebSiphon.

Under terms of the agreement, Paradigma Software will develop Valentina for
WebSiphon, a powerful add-on library for the WebSiphon web development
environment. Valentina for WebSiphon will allow users of Purity Software's
WebSiphon to interact with and deploy Valentina databases with their
WebSiphon applications. Valentina for WebSiphon will be available in a
value added bundle directly from the Purity Software online store, as well
as through domestic and international distributors of Paradigma products.

"Valentina for WebSiphon is a perfect match for users desiring speed and
power beyond flat file or desktop database solutions but aren't yet in need
of an expensive, large-scale dedicated DBMS. By developing towards the
WebSiphon API instead of relying Apple Event communication, Valentina for
WebSiphon represents an unrivaled performance value to the Mac OS
web-application developer," commented Nathan Nunn, President and CEO of
Purity Software. "This arrangement with Paradigma Software is a major win
for the Mac OS developer in need of database services on the web."

WebSiphon originally shipped into the market in 1996, and enjoys a
reputation as one of the most powerful and flexible web server products
available. Rather than using a tag-based approach to web development, like
HTML, the product's SiphonScript scripting language makes it easy for
novice and experienced users alike to create and deploy exceptionally
powerful applications. The features offered by the WebSiphon package appeal
to both new system administrators with little or no previous development
experience and programmers fluent in traditional languages such as C/C++.

Paradigma Software's Valentina 'object-relational' technology provide
designers and application developers with powerful database solutions on
multiple platforms. The Valentina database kernel indexes and searches
databases over hundreds of times faster than most database solutions
available for desktop deployment. Benchmarks comparing Valentina to mySQL,
Acius' 4D, Filemaker's FileMaker Pro and other databases are available on
the Paradigma web site.

The Valentina line of database products includes Valentina 1.6 - A compact
AppleScript controlled database server-application for MacOS, allowing
scripters to build custom solutions with other AppleScript friendly
applications; Valentina for REALbasic- A collection of add-on classes for
REAL Software's REALbasic rapid application development environment;
Valentina C++ SDK for Macintosh and Windows platforms - Valentina SDK
allows C++ programmers to build applications that harness the power of the
ultra-fast Valentina database kernel. Valentina for Macromedia Director
will be released in Q4 1999. Valentina for WebSiphon will be released in Q1
2000.
