A three tier archetecture involves a seperation of the presentation layer, the business logic and the database server.
Currently, I on my web sites, I have only simple code on the web forms to accept and verify input data from the users. I then seperate all of the business logic into classes that that execute like minded algorithims, and store like minded private data variables. However, instead of using stored procedures, I just embed the sql in the classes to hit the database server.
Would this be considered a two tier type of architecture?
Any input is appreciated.
