Post molto breve ma ricco di frasi da scolpirsi sul muro dell'ufficio. Ne riporto due che sono importanti, sopratutto per gli IT-Manager:
"A poorly designed, anti-normalized database is typically made to work using multiple layers of convoluted code. It takes a lot of extra code to keep anti-normalized data consistent. All this code is more expensive to maintain, and makes it very difficult to implement changes and new features."
"The bottom line is still that a man-day spent on database design saves, at least, a man-month of extra work later."
Leggete molto attentamente questo post di Paul Nielsen:
