Stefan Keller, University of Rapperswil (HSR), Switzerland
This project aims to extend a pure object database with 2D geospatial types.
The extension consists of the Java Topology Suite (JTS).
db4o is an open source database written in Java and .NET. It is well suited for single
user system scenarios and embedded systems running on mobile or desktop
platforms, or in real-time control systems.
Advantages of pure object oriented database technology:
•
•
•
•
•
•
•
•
Fast: Good performance and short development cycles
Simple: One line of code stores objects
Portable: Native to Java and .NET
Small: 600 KB footprint
Type safe: Native queries use programming language methods
Zero administration: Class model = database schema
Object-oriented replication
