Ciao Paolo, thanks for the advice and links. My purpose is to compare Jena SDB with Jena TDB but using Oracle as the DBMS instead of MySQL since I'm working in a project in which we have been requested to use the DBMS that is available in test and production environments in case we'll use Jena SDB. Btw Jena SDB has been removed from the BSBM after 2009.
