I would instead say "think in terms of entities of the problem domain", however. One can implement the catalog of goods using a hash-table, but for the implementor of the hash-table service, the problem domain becomes indeed "wizard" concepts. I don't see any reason why a certain class of abstractions (i.e. programming ones) is not appropriate for OO conceptualization just like any other. The real point is to use the appropriate abstractions for the domain. -- Cheers, The Rhythm is around me, The Rhythm has control.
