    Description copied from interface: Catalog
    
    Get the name of the default database for this catalog. The default database will be the current database for the catalog when user's session doesn't specify a current database. The value probably comes from configuration, will not change for the life time of the catalog instance.
    If the default database is null, users will need to set a current database themselves or qualify identifiers at least with the database name when using the catalog.
    
    Specified by:
    
    getDefaultDatabase in interface Catalog
    
    Returns:
    
    the name of the current database
