Why is database view used?

Question

Is using \"view\" in db design right method or we should handle it code side? What are the advantages or disadvantages?

Answer 1

Depends. I use them sometmies, but not that often. They are VERY usefull to expsoe decoded views on the data for use by end user (tools), like reporting applications, though. This way you can provide an end user with a simplified version of often requested information hiding some technical details.
