Sesame operates on top of a DBMS (MySQL and PostgreSQL are supported, Oracle, Poet and DB2 support are in development), but the current setup assumes that the underlying database is dedicated to triple storage. It would be interesting to see if Sesame could be adapted to fit on top of an existing database and "lift" its contents to RDF. In principle this is possible, but we haven't tried it in practice yet. As for storing BLOBs: that of course depends on the database, but since Sesame currently only stores triples, we have had no need for it. Literals are stored as large text fields, the other information is trivial anyway (though the DB schema we use is not). I hope this answers your question.
