Hello All,

I have recently joined software company, and i am told to understand code already written to follow process and methodology.
I work on DotNet windows as well as asp.net projects.

We follow 3 tier architecture.
1)User Interface layer
2)Business Objects layer
3)Data Access layer.

I want to know from where should I start looking the code ie from which layer. As we follow 3-tier architecture I want to know why has been such differentiation of layers and its advantages of using. What these layers specifically contain. Please help with your valuable inputs.

Thanks

Prasanna

Hey prasanna,

In my company we follow the same approach.

I am sure you would not be involved in all these three layers as such but yes to have knowledge of the overall working is good.
User Interface Layer-- has all your HTML, CSS, Javascript, JSPs involved
Business Objects layer has all you business logic, Beans.. EJBs if you guys are using that.
Data Access Layer-- is actually DAO calls which can be through JDBC or Hibernate and if you use EJBs then that is included in it.
Tell me exactly what your responsibility in job is.
