Hi, everyone
I got a simple question as a Jena learner: What's the relationship
between ARQ, TDB and SDB?
Through reading the documentations, my current understanding is like
this:
1. ARQ is a SPARQL query engine which parses and optimizes queries.
2. TDB and SDB are two different implementation methodology of the RDF store.
TDB uses a native No SQL database while SDB support multiple existing
relational databases.
3. ARQ has the same interface to both TDB and SDB. In respect to Java API, TDB
and SDB use different methods to manage the store connections and
authentications but that's like their only difference. Other than that, ARQ
uses exactly the same API methods to handle Datasets to both of them.
Could anyone kindly confirms or corrects my understanding please?
Yes, that's about right.
The only thing I would add is that ARQ also performs complete query
processing for memory based models. ARQ is an integral part of Jena.
