I don't think it would kill me to add an auto inc primary id. Currently both the recordID and the TypeID are set up as primary id's. Also have a unique index using both fields. The recordID though should be duplicated though as it ties the records from the various tables together to form the profile. > As far as updates and additions go, I usually keep > the two separate > when designing applications.
