Typically table A goes into enumerated type E, table B into type F, and links is an array(E) of F. You gain: - readability (e.g. you can group, reorder things, use "others") - availability of comments - availability of source control - checking by the compiler of duplicates or missing items (this is really the Ada "plus") - in SQL, gaps or duplicate will be unnoticed, your numbers won't fit, and you have no chance of tracking the problem's source - 1000's speed factor on the same server - plus it becomes so lightweight you don't need the server: you can run the program on a laptop during a meeting... _________________________ Gautier's Ada programming http://gautiersblog.blogspot.com/search/label/Ada NB: follow the above link for a valid e-mail address
