Multi-tier Web Application using ASP.NET

Print Friendly, PDF & Email

A Multi-tier Web Application includes 4 layers:

  • Web Layer (Presentation Layer)
  • Business Rules Layer
  • Data Access Layer

From the post in [1], the author based on the Microsoft Architecture exams and has a conclusion that Multi-Tiers are either physical or logical, physical being “machines”, such as client – server and logical being the layers Presentation, Business Logic and Data Access.

Internet explorer and IIS count as tiers anyway, so yes you are multi tier.
