Hi all,
Where can I find more detailed info on how can use Jena with:
1. RDBMS
* Does it support just any RDBMS?
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.
]]
* If not, and I want to use it with different (from the supported) RDMS
what should I do?
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.
1. Alternative (not TDB) graph DB
* Is it possible
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.

* If not, can it easily be done?
