db4o Symbian Database

  • Native to Symbian Quartz PersonalJava
  • Only 600K footprint
  • Seamless as serialization, but never breaks
  • Built-in synchronization with back end databases


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

Embed db4o's super-light Symbian 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

        "I am really impressed with db4o. The database is so easy to use - especially for embedded applications. db4o doesn't require any administration. It just works! And db4o's native object support makes it very easy to integrate with my Java applications."
                --Marlon Machado, IBM

        "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


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.
