org.xmldb.api.base.Database
Database is an encapsulation of the database driver functionality that is necessary to access an XML database. Each vendor must provide their own implmentation of the Database interface. The implementation is registered with the DatabaseManager to provide access to the resources of the XML database.
In general usage client applications should only access Database implementations directly during initialization.
