Advantages and Disadvantages of using 3 tier architecture

Advantages and Disadvantages of using 3 tier architecture:

In this post here we give some major advantages and disadvantages of three tier architecture of asp.net. 

Learn what is the 3 tier architecture

3-tier architecture

Advantages of using three-tier architecture:

• It makes the logical separation between business layer and presentation layer and database layer.

• Migration to new graphical environments is faster.

• As each tier is independent it is possible to enable parallel development of each tier by using different sets of developers.

• Easy to maintain and understand large project and complex project.

• Since application layer is between the database layer and presentation layer so the database layer will be more secured and client will not have direct access to the database.

• Posted data from presentation layer can be verified or validated at application layer before updating it to the database.

• Database Security can be provided at application layer.

• Application layer or middle layer or business layer can be a protection shield to the database. 

• New rules or new validation rules can be defined any time and changes made to middle layer will not effect presentation layer.

• Define any logic once within the business layer and that logic can be shared among any number of components in the presentation layer.

• We can display only necessary methods from business layer in the presentation layer.

• We can hide unnecessary methods from business layer in the presentation layer.

• Easy to apply object oriented concept

• Easy to update data provider queries.

Disadvantage of using three-tier architecture:

• To implement even small part of application it will consume lots of time.

• Need good expertise in object oriented concept (classes and objects).

• It is more complex to build.
