public class JDBCDatabase

extends Database

Support for dictionaries stored in databases. To be able to change the jdbc driver without the need for recompiling, there is not explicit loading of the driver. So you must put in the system property jdbc.drivers the name of the class to load (i.e., the driver class). You also have to set the name of the user and the password to connecto to the dbms. The system properties to set are jdbc.user and jdbc.password, respectively.

It was only used with PostgreSQL.
