Ahh, the old normalization of data question. Which normal form you do
want to use?

IMNSHO, you should NOT use the 10 category columns approach and
normalize it.

Subject: SQL Table Design

Hello All,
I'm in the process of creating a table to store a category and a
subcategory. It's possible for there to be multiple levels of this
structure, e.g. a subcategory may have another subcategory.

One of my co-workers suggested we just make a table with 10 category
columns. I don't think I really like this idea, it seems to like "old"
database design. With a recursive SQL statement I can go up or down to
find
the category hierarchy. To me this seems much more scalable.

So my question is, how are others handling this?

Thanks in advance,
