Access 2007: "I want to be normal." or, help me understand and make a table/form normal
Bevos asked on
Hello, I am new to database design and some of the experts here have said that my forms should follow standard normalization procedures to avoid future problems. I have read through a few online sources but I'm still not 100% sure how I should go about doing this in the form that I want to attach.
First normal form standard says that I should not have repeating groups, but I have many. This is because I am trying to capture all of the information in academic articles (Such as http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0014550). If I were trying to capture the patient and demographic data in table 1 from this article I would need to have four groups for race. So I thought it would be good to have in my table Race1, Race2, Race2, Race4 etc... and then Race1Per for the percent of the population etc. However, this seems to go against normalization practices. By 1NF standard I should have a table something like: [Call Number] [Race] [RacePer] and then just repeat the entry each time for the race options. How could I accomplish this with a form? I'm at a loss right now for how best to construct these forms/tables and any help would be greatly appreciated.
Thank you,
