About the architecture of project

Question

Dear All I face one question in a lot of interviews about the architecture of project. I have answered in many ways but every time interviewer seems dissatisfied. I have worked mostly on web applications which have 3 layered like Presentation Layer Business Layer Database Layer I tried to explain them about the same like presentation layer is UI business layer consist of business logic and common db functions which communicates with database(SQL) to insertselect and update data. Is there any thing wrong that I am explaining if yes then please suggest the appropriate answer for this question or if there is any other way i can explain Thanks in advance.

Here are my thoughts. In your statement you said that Business Layer consists of Business Logic and Common DB functions. I would say Business Layer should NOT have common DB functions. Only Data Layer should consist of all Data Entities Data Utilities and DB functions. In addition to this you can talk about design patterns that are used in each layer if any. For example MVC/MVVM pattern for UI Unit of Work/Application Facade design patterns for Business Logic and Repository pattern for Data Layer. Thanks Sakthi.

Hi In a nutshell technology (whether ASP .Net Web forms or ASP .Net MVC) doesn't matter. Design patterns are common to all the technologies. Your project must use some design pattern better you can talk to your seniors and get it understanding. Since you're growing you should start learning design pattern. It will help you in future when you design new applications. Don't try to learn all the design patterns together. Start learning with simple/easy one and continue with the hard one. Small drops one day will become ocean. You should be learning in such way that you never forgot that. Hope I'm make sense here. Thanks Sakthi.

Dear Sakthivel Thanks for replying Actually this was a typing error I mean that business layer consists of business logic and data layer consist of common db layer which communicates to database. I have not worked on mvc and mvvm also I don't have much knowlege about design pattern. I have only worked on asp.net web forms till now so in that case what should be the appropriate answer>
