# The elements are all optional except scheme and path:
# scheme:: The name of a DBMS for which you have a do_\<scheme\> adapter gem installed. If scheme is *jdbc*, the actual DBMS is in the _path_ followed by a colon.
# user:: The name of the user to authenticate to the database
# password:: The password to use in authentication
# host:: The domain name (defaulting to localhost) where the database is available
# port:: The TCP/IP port number to use for the connection
# path:: The name or path to the database
# query:: Parameters for the connection, for example encoding=utf8
# fragment:: Not currently known to be in use, but available to the adapters
