Hi all,

db4o is proud to announce the first full-featured beta version of "db4o -
database for objects".

If you look at the JDBC overhead for storing data, it is obvious, that
improvements are possible:

objects => strings => JDBC => transport layer =>
SQL parser => database engine memory => tables


We reduce to the necessary:

objects => byte arrays => storage medium


A benchmark for a comparison of db4o flat data performance against JDBC is
included with the download.

Complex object structures are even more in our favour.
How do you store ancestors in tables?
Why do strings need a fixed length?


Further strengths of db4o:
- 50k jar file, ideal for web redistribution and low-resource environments
- compact database file
- automatic object recognition
- query-by-example interface
- navigation by activating members


Learning db4o is very simple.
Take an hour to work through the 20 samples.


Try us,
any feedback would be greatly appreciated.


Regards,
Carl
