db4o is designed to be a simple, easy-to-use, and fast, native object database. Software developers using popular Java and .NET object-oriented frameworks know that using object databases is a more natural way to get work done. Developers have three ways to storing and retrieving data: relational, non-native object and native object.

Relational databases, such as Oracle, IBM's DB2 and Microsoft's SQL server, store data in a tabular, row-and-column metaphor. The organization of traditional data in a relational database is easy to understand. The concept took off and today most data is stored in relational databases.

However, as object-oriented models became popular, developers were spending time trying to map objects into a relational database. Today, developers are forced to rely on relational-to-object mappers, but this technology compromise adds a layer of complexity and degrades performance. It is best suited for organizations that rely on legacy data.

Non-native object databases came on to the market in the early 1990s with great fanfare. But their promise was largely unfulfilled. Developers found the technology expensive, complex and hard to use. The first native object databases had similar shortcomings.

db4o is based on new native object database technology. db4o offers .NET and Java developers the simplest and easiest way to store objects. db4o is the only native object database designed for both Java and .NET, supplied as one single programming library (Java: .jar /.NET: .dll) to be included with developer applications.

Here are some key features of "db4o":

One line of code to store objects

Native Java / .NET

Class model == database schema

Smooth production process

Automatic schema versioning

Query by example

S.O.D.A. active queries

250kB footprint

Saves more than 50% costs to develop your application

Saves more than 50% time to release your application

No need for training and administration

Build lean, structured and manageable code

Improve your software lifecycle with better refactorability and re-use

What's New in This Release:

This release comes with a new BTree architecture and major performance enhancements resulting from a new query processor that runs on the new BTrees.

Deterministic immediate query responses were made possible using a new "Lazy Query Evaluation" algorithm.
