We generally split our application into 3-Layers1)Presentation Layer ( Where we keep all web forms Master Pages and User Controls).
2)Business Layer (Where we keep business logic). e.g Code related to manipulating data Custom Exception classes Custom Control classes Login related code if any etc. etc.
3)Data Access Layer (Where we keep code used to interact with DB). e.g. We can have the methods which are using SQL Helper (Application Block).
