db4objects Makes Storing and Retrieving Objects Transparent
SAN MATEO, Calif., January 22, 2008 – db4objects (www.db4o.com), creator of the leading open source object
database for Java and .NET, has announced availability of a development release
of db4o version 7.1. The new version features Transparent Update, which automates
the storage of objects in any Java or .NET application into a db4o database.
In version 7.0, db4o introduces Transparent Activation that eliminates the need
to specify the activation depth of object graphs by automatically loading only the
absolute minimum from disk. The result is less memory consumption and a boost in
performance. Transparent Update provides the symmetric equivalent for storing (persisting)
objects. With Transparent Update there is no need to define the depth of the object
to be updated or to use "set." db4o automatically detects when objects are updated
and enlists them for storing upon transaction commit. This feature not only simplifies
coding, it also leads to faster execution times. The application only stores exactly
what is needed.
"The combination of Transparent Activation and Transparent Update results in what
we call Transparent Persistence," said Rodrigo de Oliveira, lead at the db4o Project
Steering Committee. "Transparent Persistence makes dealing with persistence a non-issue.
It all works efficiently without burdening the developer. It enables them to focus
entirely on application development without having to write persistence code or
consider object graph details."
"Transparent persistence together with db4o’s answer to the impedance mismatch makes
a developer’s life really simple” said Edwin Sanchez, IT Solutions Delivery Manager
at A. Magsaysay, Inc. “In the end you get simpler development, more deliveries,
and more accomplishments. For developers who are already experts with RDBMS, explicitly
specifying an activation depth when using db4o may be alien to them. Now there is
no need to do so."
db4objects customers have stated that as much as 50% of an application’s code base
can be persistence related. As Transparent Persistence takes care of storing and
retrieving objects in the background with no developer intervention, application
code is cleaner and simpler and therefore easier to maintain. In short, it results
in better and faster code.
