The DAL can pass parameters to a stored procedure, send asynchronous queries to the server and receive cashed result sets in a highly object-oriented way, notifying the caller UOAL to traverse through the result set. The description of the in parameters and result sets are dynamically created by calling system stored procedures on the server.
