Furthermore, what is business layer in C#?

It is a software pattern that separates components of an application into separate logical layers to establish code boundaries, promote flexibility, and allow reuse. Business Logic Layer (BLL): Application processing. Coordinates data between the UI and DAL. Data Access Layer (DAL): Where data management occurs.

What is the difference between data access layer and business logic layer?

The data access layer provides a centralized location for all calls into the database, and thus makes it easier to port the application to other database systems. To maximize reuse opportunities, business logic components should not contain any behavior or application logic that is specific to a use case or user story.

What is the difference between MVC and 3 tier architecture?

MVC is a pattern used to make UI code easier to maintain and test. When the MVC pattern is used a larger portion of the UI code can be unit tested. 3 tier architecture is a pattern used for a completely different reason. It separates the entire application into meaningful "groups": UI, Business Logic, Data Storage.
