information about a database connection specification.

The URL object is created automatically when
:func:`~sqlalchemy.engine.create_engine` is called with a string
argument; alternatively, the URL is a public-facing construct which can
be used directly and is also accepted directly by ``create_engine()``.

    Represent the components of a URL used to connect to a database.

    This object is suitable to be passed directly to a
    :func:`~sqlalchemy.create_engine` call.  The fields of the URL are parsed
    from a string by the :func:`.make_url` function.  the string
    format of the URL is an RFC-1738-style string.

    All initialization parameters are available as public attributes.

    :param drivername: the name of the database backend.
      This name will correspond to a module in sqlalchemy/databases
      or a third party plug-in.

    :param username: The user name.

    :param password: database password.

    :param host: The name of the host.

    :param port: The port number.

    :param database: The database name.

    :param query: A dictionary of options to be passed to the
      dialect and/or the DBAPI upon connect.
