# 3
Data Access Layer or DAL in an application is the layer which 
takes care of interaction with database. In DAL , generally 
Insert, Update and Delete Queries are written. DAL sits 
between database and the Business layer.

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.
