I am working on a database that I did not design. The previous designer put calculations in the child records. For instance if there is a set of conditions that needs to be met he would have an If statement the evalutated all the conditions and then set itself to 1, and then relate to the number 1 in the parent. Rather then have all the contitions in the parents and then simply get the Child records that way.
My question is how much of a performance hit is taken on this and also I was under the impression that you could not get unstored records to show up in the child records.
