TDB is a component of Jena for RDF storage and query. It supports the full range of Jena APIs. TDB can be used as a high performance RDF store on a single machine. This documentation describes the latest version, unless otherwise noted.
This is the documentation for the current standard version of TDB. This is also called TDB1 to distinguish it from the next generation version TDB2
TDB1 and TDB2 databases are not compatible.
A TDB store can be accessed and managed with the provided command line scripts and via the Jena API. When accessed using transactions a TDB dataset is protected against corruption, unexpected process terminations and system crashes.
A TDB dataset should only be directly accessed from a single JVM at a time otherwise data corruption may occur. From 1.1.0 onwards TDB includes automatic protection against multi-JVM usage which prevents this under most circumstances.
If you wish to share a TDB dataset between multiple applications please use our Fuseki component which provides a SPARQL server that can use TDB for persistent storage and provides the SPARQL protocols for query, update and REST update over HTTP.
