| DBConnectionManager | | class DBConnectionManager (Code) | | This class is a Singleton that provides access to the
connection pool. A client gets access to the single
instance through the static getInstance() method
and can then check-out and check-in connections from a pool.
When the client shuts down it should call the release() method
to close all opened connections and do other clean up.
