SDB 1.0
=======

SDB is a SPARQL database subsystem for Jena. It provides for large
scale storage and query of RDF datasets using conventional SQL
databases. The database tools for load balancing, security, clustering,
backup and administration can all be used to manage the installation.

Supported databases:
* Oracle, 10gR2 & 11g including Oracle Express,
* IBM DB2 9 including DB Express
* Microsoft SQL Server 2005 including SQL Server Express,
* PostgreSQL v8,
* MySQL 5.0 (>=5.0.22),
* HSQLDB 1.8,
* Apache Derby 10.2.

Documentation:

SDB requires Java5.

We are actively seeking feedback on SDB - both good and bad.
If it works, please tell us - if it doesn't work, please tell us!
