DAL is a class which you can for talking to database. In
this case you do not need to worry about creating DB
connection, destroy db objects, connection pooling.
Everything is handled by DAL for you. You only need to
create class derived from DAL and define sored procedures
and classes for storing result from stored procedures.
This is very convenient way of talking to DB.

used in application Design architecture. DAL used in
UI ->BL->DAL->DB
The IO from UI is passed to BL. The BL talks with DAL for
retriving and updating values in the database. DAL forms a
bridge between the Buisness Logic (BL) and the Database (DB).
