db4o Mobile Database for Java and .NET

• Native to J2ME, Symbian, Compact Framework - and more
• Only 600K footprint
• Seamless as serialization, but never breaks
• Built-in synchronization with back end databases

Use Object-Oriented Mobile Database Technology...
While Your Competitors Still Struggle With Flat Files or SQL.

Embed db4o's super-light mobile database engine into your mobile software application and store any object structure with only one line of code - no more mapping required!

Powerful and lean at the same time, you can now build more data- and feature-rich applications, that propel you far ahead of competition and that make your users and customers cheer.

Enjoy superior performance, zero-administration, transaction safety, encryption, automatic deployment, cross-platform deployability, shared memory processing, and much more. Out of the box.

Download and test drive the world's most popular object database! It's free and open source under the GPL, no registration is required!

        "db4o's mobile database gave us a clear advantage over the competition. It was proven to use very little resources - to be fast, lean, and simple to deploy - and also to be very affordable in high volumes."
                --Christian Herold, CEO Mobilanten

        "The database has been nothing short of amazing. Just the ability to modify the structure and it automatically updates the versions is worth its weight in gold."
                --Victor Boba, CEO BOCA Software

        "CF Database Engine Continued... Man, that database db4o which I mentioned last post is EASY TO USE! Seriously easy. Dead simple to implement too. Even for me :-)"
                --Robin, Blogger

Sync and Store Your Mobile Data in Partially Connected Setups

The db4o Replication System (dRS) enables users to build applications that synchronize objects bi-directionally between db4o's mobile database instances and all common relational databases such as Oracle or MySQL, typically running in server-centric environments.

The dRS is 100% object-oriented and specifically designed for the mobile business environment.
You can shave off up to 90% of development time in comparison to using replication through relational database (RDBMS) technology which is inherently incompatible to object-oriented Java and .NET.
