Hi all,
I have a doubt regarding adding references to website.
What type of problems I may face if add 'DataAccess' reference to 'web site'.
As per my knowledge it is mandatory to give business facade and common class references to website.

You are asking about Layering or some other question. Keeping a intermediate layer is always best, between DataAccess and Website

You may get error messages like - "Are you sure to add the reference ? If not then why did you waste your time in writing the DataAccess logic..." ;)

Well, as per feature working, no problem. By adding a DataAccess reference, you are removing business layer segregating the UI & DA layers. Thus, converting your application architecture into 2-Tier application.
It is NOT mandatory to have a BL between UI & DA. One of the general good architecture used is 3-Tier where BL keeps UI & DA separate and acts as mediator. There are benefits of this structure like easy maintenance and no coupling of DB with UI. Easy change of DB layer without affecting UI or vice-versa.
In case you want to know/read more on 3-tier architecture, please have a look at these:
