what is n tier ?

Answer

3-Tier architecture generally contains UI or Presentation
Layer, Business Access Layer (BAL) or Business Logic Layer
and Data Access Layer (DAL).

Presentation Layer (UI)
Presentation layer cotains pages like .aspx or windows form
where data is presented to the user or input is taken from
the user.

Business Access Layer (BAL) or Business Logic Layer
BAL contains business logic, validations or calculations
related with the data, if needed. I will call it Business
Access Layer in my demo.


Data Access Layer (DAL)
DAL contains methods that helps business layer to connect
the data and perform required action, might be returning
data or manipulating data (insert, update, delete etc).

must provide our own code to do this if required, but this
gives us a bit more freedom in what we do
