/** Example of creating a TDB-backed model.
 *  The preferred way is to create a dataset then get the mode required from the dataset.
 *  The dataset can be used for SPARQL query and update
 *  but the Model (or Graph) can also be used.
 *  
 *  All the Jena APIs work on the model.
 *   
 *  Calling TDBFactory is the only place TDB-specific code is needed.
