Surrogate keys are generally integers calculated from generators, which
have no meaning except being unique and used in relationships. Normally you
wouldn't show these values to your users (if you are a programmer, they are
of course visible in the database). In IBO you generally assign
GeneratorLinks, whereas IBX/BDE assign the values in a BEFORE INSERT
trigger (I think).
