db4objects, creators of the open source object database for Java and .NET, have announced the launch of the db4o Replication System (dRS), which enables users to build applications that synchronize objects bi-directionally between distributed instances of db4o's object database, all common relational databases such as Oracle or MySQL, and any combination thereof.

Built upon the popular Hibernate product, the dRS makes db4o's native object persistence architecture available to all Java and .NET developers while staying fully data compatible with existing IT environments using relational database technology.

"The launch of the dRS strengthens db4o's position as an embedded, client-centric data persistence solution for object-oriented environments and acknowledges the predominance of legacy RDBMSs in server-centric environments," says Chris Lanfear, Research Director at VDC. "With db4o's seamless replication, developers can now enjoy the benefits of true object orientated software programming while fully servicing corporate or infrastructural requirements to support relational database technologies. This should make db4o's object database technology appealing to a much wider audience of Java and .NET developers."

Enabling the Agile and Mobile Enterprise
The dRS is 100% object-oriented and specifically designed for agile enterprises and product developers in a fast changing and ever more mobile business environment. Software managers can shave off up to 90% of development cost and time in comparison to using replication through relational database technology that was designed for server-centric data storage in the 1980s and that is inherently incompatible with the new object-oriented software architectures of Java and .NET.

db4o's object database is optimized to be embedded in distributed applications and software-enabled devices, where resources are constrained, performance is critical, and no DBA is present.  In many cases, these client-side db4o database instances are partially connected to enterprise servers running relational databases (RDBMS) such as Oracle or MySQL. The dRS now provides automatic, uni- or bi-directional data synchronization between these distributed data sets upon connection.

"When we designed our real-time high speed train control system for Spain's AVE, we chose db4o as the core of the real-time database," said José Miguel Rubio Sánchez, IRC Technical Manager at Indra Sistemas, Spain's largest IT company.  "db4o's speed allows the system to process over 200,000 objects of system data per second – which are then aggregated and fed into the corporate network running Oracle.  We are very excited to see db4objects offering an off-the-shelf solution for this important link between the real-time database and the corporate data-center, which will save development cost and make products easier to maintain."
