re: pro- foreign key propaganda? pro- foreign key propaganda?

aka ... overloading a value with multiple characteristics can significantly improve runtime operation ... but can become an administrative burden to maintain the consistency of all the different characteristics.

reducing the number of different characteristics a value has to represent will reduce the consistency administrative burden but will typically increase the runtime overhead (navigating internal tables relating the different characteristics). Received on Wed May 21 2008 - 14:17:47 CEST
