Get a head start for your products by leveraging db4o’s cutting edge technology to achieve unprecedented levels of performance and flexibility.

Simply embed db4o’s open source object database engine into your application and store and retrieve even the most complex object structures with only one line of code.

It’s main features include the following:

- One-Line-of-Code Database: Store any object with just one line of code

- Embeddable: db4o is designed to be embedded in clients or other software components completely invisible to the end user. Thus, db4o needs no separate installation mechanism, but comes as just one easily deployable library with a very low footprint of some 400KB

- Portability and Cross-Platform Deployment: db4o supports Java’s JDK 1.1.x through 5.0 and runs on J2EE and J2SE. db4o also runs with J2ME dialects that support reflection, such as CDC, PersonalProfile, Symbian, Savaje and Zaurus.

- Native Queries: Rather than using string-based APIs (such as SQL, OQL, JDOQL, EJBQL, and SODA), NQs allow developers to simply use the programming language itself (e.g., Java, C#, or VB.NET) to access the database and thus avoid a constant, productivity-reducing context switch between programming language and data access API.
