I think this could be qualified a little. Sometimes it is enough to know that verging into certain territory will put one in over one's head. I remember learning years ago that much of electrical engineering has to do with recognizing when the 'first approximation' is sufficient for circuit design, eg., certain circuits don't require the calculation of say, impedance or capacitance, ie., so-called second or third approximations. Applying a given rdbms product seems similar, for example, it seems one could spend a few years trying to understand 3VL, or given the shortness of life, just say no and decide to avoid nulls.

(Granted that the word "approximation" in relational theory context is by itself a dangerous one to use, but that's a danger in all parallels.)
