public interface DatabaseProvider

Database provider. This database provider represents a particular type of database such as its capabilities and the ability to create an instance representing a running database. Since the DatabaseBuilder uses a first match algorithm and the order of databaseproviders is not guaranteed, it is recommended for each database provider to also provide a unique capability that no other database has.
