-- db4o REPLICATION SYSTEM (dRS) V1.0 LAUNCHED --
db4objects is proud to announce the launch of the db4o Replication System (dRS), powered by Hibernate, 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. 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 dRS is 100% object-oriented and specifically designed for agile enterprises and manufacturers of software-enabled products 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 which had been designed for server-centric data storage in the 1980s and is inherently incompatible to the object-oriented software architectures of Java and .NET.
db4o's object database is designed to be embedded in distributed applications and software-enabled devices, where resources are constrained, performance is critical, and no DBA is present. Examples of db4o customers' applications are Indra's High Speed Train Control System, Boeing's P8-A aircraft, or Easterndata's mobile doorstep delivery system running on off-the-shelf PDAs. In many cases, these client-side db4o database instances are partially connected to server-side enterprise IT running relational databases (RDBMS) such as Oracle or MySQL. The dRS provides automatic, uni- or bi-directional data synchronization between these distributed data sets upon connection.
The db4o Replication System (dRS) is available for db4o-to-Hibernate/RDBMS, db4o-to-db4o and Hibernate/RDBMS-to-Hibernate/RDBMS replication. dRS version 1.0 runs on Java 1.2 or later.
A free download under the GPL is available at the db4o Download Center, and an affordable commercial (non-GPL) license is available upon request.
More product information can be found here.
-- VERSION 5.1 DEV RELEASE --
Version 5.1 of db4o's object database is now available for download from the db4o Download Center. Version 5.1 features incremental improvements such as the optimization of Native Queries for Mono and enables users to replicate objects using the db4o Replication System (dRS - see above.)

-- PORTUGUESE LANGUAGE PORTAL AND REPRESENTATIVE --
db4objects has named Bizness Sistemas as the company's general representative for the Brazilian and Portuguese market, a region which ranks top in the open source world and has shown a strong adoption of db4o. Bizness Sistemas is located in Blumenau, SC, Brazil and is headed by Cássio Rogério Eskelsen, a long-time, knowledgeable db4o user.
To help users in this region, Bizness Sistemas has provided a new Portuguese portal which aggregates all resources on db4o available in Portuguese. The portal features db4o V5 product information, a success story about INDRA Sistemas' high speed train control system, as well as links to a recent article on db4o in Linha de Código and to the db4o User forums -- all available in Portuguese language.
Bizness Sistemas complements the activities of our partner Cyber Quality Control SRL in Buenos Aires, Argentina, which focusses on the Spanish speaking regions and provides the Spanish portal. German Viscuso, CQC's db4o representative, has published a new whitepaper on object database technology and db4o in Spanish language, titled "Bases de Objetos".
This new whitepaper is available for free download.
-- db4o NAMED "MOST EYE-OPENING TECHNOLOGY IN 2005" --
We are proud to see db4o being named the "most eye-opening technology" in 2005 by LogicaCMG's Java Blog:
"Most eye-opening technology: DB4O
DB4O rocks! Object oriented databases have always been a bit clumsy. Either the way they interacted with a programming language (JDO for example) or the way they are installed, setup and configured (Ozone for example) never felt comfortable. DB4O takes a fresh approach: It's embedded in the language and you can embed it into your application. Code needed to persist and re-retrieve your objects never has been that simple (I've been flabbergasted by their native queries: just write actual, no criterium api alike, java code to express a query). Forget ORM but go OO the right way!"

Here are the juiciest sound-bytes from users like yourself over the last month:
"Nice - db4o seems to be the answer to my prayers! Now I can store everything directly into an native .NET DBM without needing to convert anything :-) It's really fast too and using the object browser is nifty (I can even save everything in XML if I want to - why I would do that, though, is beyond me)."
--Blogger Torkar, 1/8/06
"I've been working for a while now with db4o, an object-oriented database. It's native Java (ie you use it from and feed it Java objects, as opposed to translating to some third-party pseudo or meta object representation as most of the original OODBMSes required you to do). It does a really straight forward job of just persisting Plain Old Java Objects. No mucking around with bytecode enhancers (like JDO) and certainly none of the self-mutilation that goes with EJB. db4o has proved fairly easy to use once you wrap your head around the fact that instead of foreign keys you just use a plain old Java variable - because of course all variables (ok, instance fields) are references in Java. Neat..."

"I'm very pleased! Db4o is truly powerful and *insanely* easy to use..."

"I get to like this fantastic software more and more now. it is so elegant solution for object orient computing."
--User "Meng", 1/24/06
"Once again, this is the coolest db anywhere!"
