Is using Natural Keys bad?

Debbie_1004338aMay 6 2013 — edited May 11 2013
Hi there. First time poster, and fairly new to the database world.

Up front, I would like to say that I am working with MySQL, but since I consider Oracle people to be some of the smartest, I figured I'd join and try to learn from the pros!!

I would like to know if it is "bad" to use Natural/Physical Keys as the Primary Key in a table?

How does this affect performance?

I have some tables which are basically "look-up" tables, and it would be much easier for me to work with Natural Keys, but I don't want to choose something that is easier for me, that would mess up my database.

Sincerely,


Debbie
