db4objects Announces db4o Database for Android

Posted on 07 December 2007 by Hatem Ben Yacoub

Db4odb4objects, provider of object oriented database for the .NET and Java, have just announced officially the availability of their solution db4o for the Android platform. Db4o is a distributed company with engineers from all over the world, but really hats off for their amazing work to make their entire solution ready for Android in record time. So for now, Android developers have full object oriented solution ready to use.

Java programmers are delighted with Android’s full object oriented platform they are frustrated by its bundling with a relational database, requiring cumbersome plumbing between objects and tables. db4o fills the gap by providing a fast and secure, native Java object database that makes storing objects and sharing of data between applications simple and easy.

It’s true that Android came with “Content providers” but as Carl Rosenberger, db4object’s Chief Software Architect, said in a blog post “this is not Java, it’s not object-oriented, it’s not even SQL.” Which is the missing element in Android platform : The object database solution.

This Tuesday we had the chance to talk to Nik Wekwerth, the VP of Marketing db4objects, and he told us about db4o solution for Android and how it could help developers to make fully advanced object oriented applications. “It’s all about simplicity” he told us, “In Java you prefer always to stay in Object Oriented. Object is more flexible than SQL, it doesn’t lock your memory”.

There are currently two applications ported to db4o, the Password Manager application and MapMe. It shows the capabilities of db4o and the simplicity of using objects to store and retrieve data. There is no real benchmark at this time Nik told us, but it’s clear from these two samples that using db4o is much easier and very simple to maintain.

Where can you use db4o ? “If you look at our customers, database usage is very large from planes, high speed trains, photocopiers, research …” Added Nik. DB4o proved its performance in many critical usage and their world class leaders customers like BMW, Boeing, Bosch, IBM, Intel, Ricoh, and Seagate, are certainly enough for Android developers to make sure that they have in hands a high level database solution.

Developers can write software applications that enable the backup of user data to a back-end server or their home PC. A consumer use case could be to start a game on the phone, freeze it, and continue playing at home in the evening. Business use cases include field force automation, data acquisition such as with RFID, and complex navigation systems that use locally cached geodata.

Db4o is open source under GPL, you can get started by downloading db4o for Android and start porting your current relational application, or start your new project in a fully object oriented environnement.
