Compatible With Open Source Technologies: Java/.NET
Compatible Hardware Platforms: Any hardware compatible with Java/.NET

db4o is the open source object database that enables Java and .NET developers to store and retrieve any application object with only one line of code, eliminating the need to predefine or maintain a separate, rigid data model.

World class innovators deploy the db4o database engine at the heart of next generation data-driven devices and applications to cache user-generated and client-side data, enabling compelling new features and achieving unprecedented performance and flexibility.

From devices and equipment to Complex Event Processing (CEP) systems db4o excels in a wide range of applications due to its performance, transparency, flexibility and ease of use.

The secret of db4o’s success is its ease of use because it is native to Java and .NET, storing data objects exactly in the way they are defined by the application. db4o therefore easily integrates into the application and performs highly reliable and scalable persistence tasks with just one single line of code, no matter how complex object structures may be. You are no longer required to predefine or maintain a separate, rigid data model, because the model is now created and updated ‘on demand’ by db4o itself during a transaction.

FEATURES & BENEFITS

• Store and retrieve data on devices, within your client-side software or anywhere in the network, with the robustness, scalability and reliability of a device-grade, ACID-safe database engine
• Build truly object-oriented applications with powerful, native retrieval options (eg. LINQ) rather than chopping strings for database access
• Build blazing fast persistence into Java or .NET applications, optimized for low memory consumption
• Change, refactor and customize software more easily because there is no need to manually keep the database schema in sync with the application schema
• Use more complex object models and object navigational graphs to build more feature rich products
