Hello
I want to create Web Application for Attendance Management System Using 3 tier Architecture.
I don't know how to use that 3 tier Architecture as I am using this for the very first time.
I have tried it with the help of some sites but it gives an error about "ConfigurationManager" and "DLL" File.

Please Explain
