Datamorphics Limited, a leading provider Java based products, announced today that it has launched Persistent Java Objects (PJO) version 1.1.

One of the greatest challenges facing Java Architects and Programmers today is the integration of Java application programs with traditional relational databases. Java programs are based on objects and many of today’s software applications are written in Java. Relational databases have existed for many years and store data based on a linear technology of rows, columns and tables. Connecting the two technologies is like trying to put a square peg into a round hole. The result is known as the impedance mismatch and poses a significant obstacle to development teams.

PJO provides an innovative approach for solving the impedance mismatch. While previous persistence products require tedious database query language or complex object relational mapping, PJO provides transparent storage and retrieval of data. PJO operates as a layer over a traditional database, and supports all the leading databases. PJO provides a very simple solution that is easily understood and quick to implement.

PJO is particularly well suited to managing very complex relationships. Java applications that manage highly complex relationships such as geographical mapping, financial transactions, and inventory management are well suited to take benefit from PJO advanced architecture.

“PJO provides Java Architects and Developers with an excellent option for taming the impedance mismatch.” said Tony Walker, president and CEO of Datamorphics. “It allows Java Architects and Developers to work with an object oriented view of their data, rather than forcing the design to meet the constraints of a relational database.”

Datamorphics Ltd. is a privately held company based in Ottawa Canada. The company is a leading provider of innovative solutions for Java Architects and Developers. For more information, please visit
