I have a customer table : firstname , lastname.
i have customer class: fisrtname. lastname.
In three tier architecture, if i authenticate the custmoer using firstname and lastname.
deafault.aspx: i use form with two textboes for firstname and lastname.
default.aspx.cs: on click of a button in i assign the text boxes values to set properties of firstname and lastname of customer.cs class
i have a event handler in custmer clas to pass the object to customer DA class.
the DA class check the validity in the customer table. and allows access.
This is my understanding of n tier architecture.
If i add few more columns later to customer table. if i need to use them for authentication, i have to add in all layers.
Is there any approach where in this situation is taken care of?
I am beginner to asp.net.
