Title: Data modeling - what is a"PFK"?
Post by: davidb on September 06, 2006, 11:14:30 am

HI,

I recently started using EA as my data modeling tool and I'm now facing a situation where I have no idea how to solve the problem: on my diagram one of the table has a "PFK" attribute. How can a Primary Key become a Foreign Key?

I don't know how to remove this FK attribute. I looked at all the associations and they all seem OK. In fact, I don't know why this problem occured in the first place.

Has anybody ever faced a similar situation before?

Thanks

This is if (a part) of the primary key is derived from a foreign keys primary (in class notation you will then use the filled diamond). You can right click the association in order to change the FK behavior. Also read the help which describes handling of FKs.
