Tamino can be accessed via ODBC/JDBC, but…!
Tamino contains actually two databases: The native XML store, and a SQL engine in parallel. Unless you licensed this SQL engine, it will stay turned off. Once turned on, Tamino can act as SQL server as well, with all benefits and drawbacks of relational data.
Of course it is possible to access this relational data via XQuery, but it is not possible to access XML data stored natively via the SQL interface.
