db4o2D - Object Database Extension for 2D Geospatial Types

Poster | Presented

  • Stefan Keller, HSR - University Rapperswil

In this contribution we present a pure object database and extend it 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. The class model is the database schema. One line of code stores any object. db4o offers Native Queries: Rather than using string-based APIs - such as SQL, JDOQL or EJBQ - NQs allow developers to simply use the programming language itself (e.g., Java or C#) to access the database. So queries become type-safe and refactorable. Future work includes a multidimensional index.
