Simple Object Persistence with the db4o Object Database. db4o has been chosen for applications in embedded systems in which zero administration, reliability, and low footprint are critical features. In Germany, BMW Car IT, for example, uses it in an embed
db4o has some interesting features:
- No impedance mismatch–objects are stored as they are
- Automatic management of the database schema
- No changes to classes to make them storable
- Seamless Java (or .NET) language binding
- Automated data bindings
- Installation by adding a single 250Kb library file (Java jar or .NET DLL)
- A single database file
- Automatic schema versioning
- Query-By-Example
- S.O.D.A. (Simple Object Database Access), an open
source query API
