Re: Query Me This -- two references to another tables field



Carol,

Opinions may vary on this. I am not sure why someone else has advised you the way they have. One-to-one relationships add complexity to the data structure, so there has to be a good reason to introduce this extra complexity. In my opinion, your database doesn't even begin to qualify. If it was mine, all of the information you listed would absolutely, definitely be in the tblContacts table, where you had it in the first place. You will be able to get it to work by having it in a separate table, but I wouldn't even think about it.

I would say that about 50% of the contacts are NOT referred by someone else
(they find the organization on their own), or, they are existing contacts
from a flat-file DB that is being ported to Access, which did not collect
this information (some of which are 6 - 7 years old) -- when the DB is ready
to go, we will attempt to collect this original referral information for as
many of our existing contacts as possible, but you know how people are about
responding to a survey at times, so we may very well not get this
information.  What is your opinion on that percentage of total contacts (400
of about around 800 at this point, and growing quickly) in terms of blanks
if all of this is tracked in the basic contact table?

Also, we want to gather a number of different pieces of information about
the referral, even if self-referred -- 1. Type of first contact with the organization
2. Who referred them, if it is currently a contact in the DB
3. How they found us, if there was no person referring them
4. Date of first contact with organization
5. Notes about the first contact


I actually started out with all this in the tblContact, but removed it and
began working with a separate table at the suggestion of someone in this NG.
Since I am not yet truly adept at append, join, etc., I have erred
consistently on the side of more rather than less tables.

Thanks again for your help,
Carol
