I'm just wanting to get the opinion of some of you folks experienced with this before I go off doing something that might be really dumb. It seems to be standard practice to use a different DAO for each class you need stored in a database. I understand the reason for this in most cases, but hibernate allows you to find any kind of class with a get or a find call. Would creating a single DAO that can handle any class be beneficial, or are there serious disadvantages to doing so?
