Hi Rick - I'm trying to do a simple genealogy, There are individual people, their parents, and sources of that information. I have a PEOPLE table, listing the person (INDI column) and the source (SOUR column), and then some information, and the listing of the parents PARE1 and PARE2, each of which match with some INDI in that same PEOPLE table. I can have multiple INDI's in the PEOPLE table corresponding to information on one individual but from different sources, but the (INDI,SOUR) pair will always define a unique row in the PEOPLE table. Then I have a SOURCES table, and the SOUR in the PEOPLE table points to a particular row in the SOURCES table, which gives info on that source.
Are you saying that I don't need to link these tables in any way? I guess that would mean I would not have to define any primary keys either?
Thanks for your help on this..
Paul
