Project Architecture diagram sample

Common mistakes :- Many 
developers make a common mistake of answering this question by saying that we 
have used C# , SQL server , ASP.NET etc. But please do note that the question 
is, what is the architecture of your project and not technology.

So a typical answer will be something as 
below. Please note your answer will vary as per your architecture and structure.

"My current architecture is a simple 3 tier 
architecture with UI in ASP.NET , middle layer are simple .NET classes and DAL 
is using enterprise application blocks.


The UI  is responsible to take user inputs , all my 
business validations are centrally located in middle layer and the data access 
layer is responsible to execute stored procedured and SQL queries to SQL Server.


Strongly typed business objects are used to pass data from one layer to 
other layer. The database of the project is in a 3rd normal form."



So first start with the overall architecture , talk about each layer , how data 
is passed between each layer and the database design structure.



One very important tip if you can draw a diagram and explain....I think you have
the job.
