Subject: DAO

I have a basic doubt about DAO. I know that depends but I need to start.

My example is:

I have a table Customer.

How do I implement the DAO Patterns for the SQLs: insert, update and
delete ?

Where do the SQLs stay ? Entity bean, class or Session Bean? Do I
implement a session bean call a class with the procedures SQL?

The Pet Store doesn't have the insert methods. Is there a another good
sample?
