The definition as I understand it. Notably, a venerable dictionary that I have gives as an example (of prevarication) things very akin to Robert Martins' tedious self- righteous tirade . Anyway, where is Nygaard and Dahls' petri dish that they discovered, or accidently spilled something into ?? For such a petri dish does not appear in their recollections of the origins of Simula ...

I have yet to find a tool/paradigm that magically simplifies that all. I have yet to see a good book addressing the management of business logic/rules (both inside and outside of OO). The few that bother to dictate "good practices" don't bother to justify them well. Hierarchies and sub-type classifications are NOT the solution. Access has kind of a goofy GUI engine, but it still beats a lot of web-based UIs. Access is also fairly versatile in that it can host self-standing applicationss, or be kind of a front end to big-iron RDBMS, letting the RDBMS do the heavy lifting. Here are my grades for it: GUI system: B- Client-side DB engine: B (mostly because the competitors are really lame) Language: C SQL syntax: C Reliability: D Open Source: F -T-

In English the primary meaning given by Websters is /the/ meaning - to prevaricate is neither to lie nor tell the truth but to avoid doing either. |
