6. What is 3-Tier Architecture
• A 3 way interaction in a client/server
environment.
• The user interface is stored in the client
• The bulk of the business application logic is
stored in one or more servers
• The data are stored in a database server.

10. If the Application tier server is down and caching is
sufficient, the Presentation tier can process Web
requests using the cache.

11. 3-Tier Disadvantages
Increased Complexity / Effort
o In General 3-tier Architecture is more complex to
build compared to 2-tier Architecture.
o Point of Communication are doubled.

13. User Interface Layer

14. Folder Structure for the 3 tier Application

15. Presentation Layer

16. • Application layer is the form which provides
the user interface to either programmer of
end user. Programmer uses this layer for
designing purpose and to get or set the data
back and forth.

17. Business Layer

18. This layer is a class which we use to write the
function which works as a mediator to transfer the
data from Application or presentation layer data
layer. In the three tier architecture we never let
the data access layer to interact with the
presentation layer.

19. Data Layer

20. Presentation Layer

21. Business Layer

22. Data Layer

23. This layer is also a class which we use to get or set the
data to the database back and forth. This layer only
interacts with the database. We write the database
queries or use stored procedures to access the data
from the database or to perform any operation to the
database.
