db4objects 6.0 released as a production release

Hi Jonathan,

  db4object, creator of the open source object database, announced  
the production-ready release of db4o Version6.0 which is up to 10x  
faster and 90% leaner (less memory consumption) than Version 5.   
Version 6 also supports a new server side cursor technology for  
deterministic response times when querying in C/S multi-user  
environments, which allows even more Java and .NET developers to now  
take advantage of db4o’s ultra-easy object storage capabilities.
  Thanks to the feedback of the world’s largest community of object  
database users – more than 15,000 registered developers and growing  
–  who have downloaded 12,400 copies of the development version over  
a period of only 4 weeks, many bugs were fixed along with the  
introduction of an impressive set of new features. Based on this  
unprecedented support and their innumerable contributions, db4o has  
established a mainstream alternative for object persistence, versus  
traditional relational databases like Oracle or MySQL.
Are you interested in an interview to learn more about Version 6 and  
about the amazing customer and developer support of the database? I  
am happy to set up an interview with Christof Wittig, db4object's  
CEO. Let me know what day/time works for you.
Development managers at leading companies like Boeing, Bosch, Intel,  
Siemens, Seagate and Ricoh are already using db4o to slash  
development costs and time and stay ahead of their competition – in  
part because db4o's technology eliminates the tedious work required  
to solve the classic “impedance mismatch" problem.  This occurs  
whenever Java or .NET application objects must be painstaking  
converted for compatibility with a relational database management  
system (RDBMS).

Version 6.0 features significant performance improvements, both for  
in-process, embedded mode as well as for client/server operation. In  
comparison to Version 5, in-process transactions with db4o now run up  
to 10 times faster (e.g., on Commits of added objects), while memory  
consumption is now constant at 3MB in all but one Pole Position  
benchmark test cases, reduced from up to 27MB in Version 5.

In addition, the new release features:

Lazy queries, a new server-side cursor technology to boost client- 
server performance
.NET API changes make db4o as native to .NET as it is to Java
Documentation "2.0", the ultimate WIKI-based reference documentation  
infrastructure
Fast defragmentation makes it now up to 14 times faster to defrag  
your database files


Version 6 also comes with updates of two powerful components: the  
db4o Replication System (dRS) v6.0, to ensure compatibility to  
backend relational databases like Oracle and MySQL, and the new  
ObjectManager v6.0, which helps developers browse and debug db4o  
databases in an object-oriented manner.

The community hailed the new version when it first got hold of the  
development (beta) version on November 14. Extensive feedback, in  
person - during the global db4o Roadshow with stops in San Francisco,  
Boston, Tokyo, Seoul, Beijing, Shanghai, Guangzhou, Munich, Paris,  
Berlin, and London - as well as online, was overwhelmingly positive,  
such as Blogger Ward Bekker's: "In my eyes the developers of DB4O  
really got it. Have very low minimal hardware requirements, test the  
user experience against that and make the performance a big priority."

I look forward to hear from you.

All the best,
