Thanks Andy,
I didn’t quite understand this:
“1/ Use SPARQL (interface RDFConnection) to connect to a remote triple
store. SPARQL tripe stores are very good at implementing the standards.”
Does it mean that the graph DB I wanna use, should (out-of-the-box) support
triples and SPARQL or this is the part that I should implement in order to use
it with Jena?
Can you, please, point me, to examples how to:
1. Implement SQL adapter
2. Implement usage of alternative graph DB
Happy holidays!
Stefan

The supported databases are described in the documentation:
https://jena.apache.org/documentation/sdb/databases_supported.html
Note:

Use of SDB for new applications is not recommended.
This component is "maintenance only".
TDB is faster, more scalable and better supported than SDB.

Do you need it to be an SQL database? (Someone was doing HAMA at one
time but we didn't hear back from them).
You have to write the SQL adapter - SQL syntax, especially for DDL, is
quite variable. There are various examples to start with.
But SDB does not have the scale and speed of a native graph database.

Yes.
1/ Use SPARQL (interface RDFConnection) to connect to a remote triple
store. SPARQL tripe stores are very good at implementing the standards.
2/ See if the store of your choice offers a Jena adapter.
