A promising 3 tire architecture for professionals

As its name suggest it really facilitates any type of CRUD operation. I have developed some data flows to demonstrate how it works. Error tracking and auto logging enabled and all settings are placed into Web.config. Necessary database and stored procedure scripts are provided with this submission. I hope you will get it as professional and useful for your next web application for stable flow. Possibility exists to make this architecture richer and if you get it useful please vote for it. Thanx.
