Normalisation
Hi i am trying to normalise a report. I am have trouble converting from 1NF
to 2NF. All the fields in UNF are repeated data, therefore all go to 1NF, but they are all under 1 Primary Key. So they should go straight to 2NF because there is no compound key? Would i have to seperate them when going to 3NF? if so, i know that i would need more table than the ones produced if i go through the above route. How do you go about this? Also, in UNF do i list all the fields on the report or can i list all the fields plus more which is either required but not stated on the report or add a few fields to make it understabdable, e.g. Subject ID, Topic ID... If this was the case, i could create a partial key? Any help would be most greatful! |

I don't work with people's interpretations of 1NF or whatever. If you
provide some table structures, primary and foreign keys, and sample data, I might be able to help. -- Duane Hookom MS Access MVP "kmistry" wrote in message ... Hi i am trying to normalise a report.
