OK if I get this right, TDB is the actual database storing all triples/n-quads, and Fuseki is a layer on top of it whose purpose is to parse SPARQL queries and retrieve triples from TDB.Right?
YES,and if you are not working on a Semantic Web app with a database basing on triples you don't need Fuseki because of 'other' query languages...
