I am working on developing an application for my personal blog. I am currently still laying out the structure of my database. I am pretty new at this so I am sorry in advance if this is a really basic question. I am in the process of making everything as normalized as I can get it. From what I read and researched it is hard to UPDATE a field that is part of a lookup table. Is this true? Is there a way that I can update the lookup table without removing the reference?
