Software Tree Releases New Mission Critical J-Database Exchange™ (JDX™) Product at JavaOneSM Conference

San Jose, CA -- March 24, 1998 --A new mission critical Java™-enabled software product for Internet / Intranet applications arrived today. Software Tree, Inc. has released JDX 1.0, a platform independent software product for exchanging business objects between Java programs and SQL relational databases. An elaborate customer application using JDX will be demonstrated in San Francisco at JavaOne Booth #445.

The JDX 1.0 Product:
The J-Database Exchange (JDX) product is a high-performance and cost-effective solution for integrating Java objects with relational data. JDX bridges the gap between the Java object model and the SQL relational model by providing a very natural object-oriented interface to store and retrieve Java objects. JDX exploits the standard JDBC™ interface to link to various relational backend systems, including Microsoft (Nasdaq: MSFT) SQL Server, Oracle (Nasdaq: ORCL) , IBM (NYSE: IBM) DB2, Sybase (Nasdaq: SYBS), Borland (Nasdaq: BORL) Interbase, Cloudscape JBMS and Microsoft Access.

JDX provides a very efficient and scaleable solution to a common need for application programmers: persistence of business objects. JDX provides support for complex object-modeling and for object integration with legacy data. All-Java implementation of JDX makes it portable on every Java-enabled platform.

Founder & CEO, Damodar Periwal states, "You don't have to throw away the advantages of relational technology and your legacy data in order to get the object-oriented benefits of the Java language and platform. JDX will put the mature relational infrastructure to excellent use for your object-oriented applications."

Periwal has filed for a Patent covering the innovative software technologies used in JDX. He was an inventor under original U.S. Patent 5.644.768 for work done at Borland International on Systems and Methods for Sharing Resources in a Multi-User Environment.

JDX Use :
Internet/Intranet enterprise applications require distributed, object-oriented technologies based upon open industry standards. JDX provides the enabling infrastructure software that links relational database sources to object-oriented Java applications.
