"Every language has a killer app, an application that catapults a language to popularity. DB4O is my killer app - it is the tool that draws me to Java."

-- 6.2.501 ADDS COMMITTED CALLBACKS AND PUSHED UPDATES, IMPROVES C# READABILITY --
The development version db4o 6.2 adds
committed callbacks and pushed updates.
You can now register a listener for the committed event and use it to keep all clients
informed about changes committed by other clients. One use case is that you can
keep objects on all clients in sync with committed changes if you refresh objects
from within the listener. That way you can make sure that the local cache always
is updated automatically and you never have to call #refresh() upon retrieval of
objects in a query. More about this feature
here.
The free download of development version db4o 6.2.501 is available at the
db4o Download Center.
Improving C# readability
As some of you may know, a majority of the C# sources for db4o.net are generated
from the Java version. This is possible because of the similarities of the two platforms,
and of the two languages. To simplify the task we created a converter that takes
care of translating the Java sources to plain C# sources.
So far the code we generated
was readable by the C# compiler but it was a little harder to read for humans.
Now, with the new and improved converter, we organize the imports for every C# source
file. It provides perfectly valid C# code that is much more readable.
More about this feature in
here.
-- 6.1.501 - LATEST ITERATION OF db4o 6.1 STABLE VERSION RELEASED --

-- DB4O SHOWING NAV-DEMO WITH NAND DRIVE AT JavaOne --
Come and see db4objects' navigation system demo at the Sun booth at JavaOne 2007.
The demo is based on a system developed in conjunction with a leading Japanese car
manufacturer. Users will be able to set up a simulated environment with streets
and obstacles such as trees and lakes to test the Dijkstra search algorithm that
can find the shortest route between two points. This demo highlights the perfect
marriage of db4o and NAND drives.
Learn how db4o maximizes database performance and optimizes NAND life by visiting
us at the Sun booth at JavaOne Conference
in the Moscone Center in San Francisco, CA.
