Table Design Question

[lkeeton]

I have a question about tables. If I have 17 fields in my table, and had about 
4 fields where actually the table search and scans actually go to(Where key > 
4 is an example what I mean). Is it more efficient just to keep these fields 
in the table in that their in now, or should I make this relational and put 
that field a foreign key in another table. So in the other table I have the 
item# and this key(12345678) which is auto-incremented. I don't know if this 
will make a difference, if it will I would be glad to know about it.\

Thanks
