        Sybase, Schmybase, Oracle, Schmoracle -- the concepts are still the same.� Developers create tables and indexes and then write SQL, thinking that the RDBMS is at fault if performance doesn't match expectations.

        They have to understand that the structures they have created or the queries they have written may simply be inefficient, expending too much work.� I don't know how to measure that in Sybase, but I'm reasonably sure that there must be a way.

        I used to joke that I could get Oracle�ERP/Apps�to run on a Palm Pilot if I were permitted to really�tune the SQL.� The work performed by an application is not an immutable monolith, especially with the Oracle RDBMS and all of the performance statistics it keeps.� It is very much susceptible to improvement.

        First, they must make a reasonable attempt to *fix* the problem (by making SQL more efficient).� If that doesn't work, then�they should�*accomodate* the problem by buying more hardware, increasing buffer sizes, etc.� The key with the latter approach�is to realize that you haven't fixed anything, only accomodated it by throwing resources at it.

        Pop quiz:� Think of a parent with a spoiled child who is making a scene in public.� How do you quiet the child?� :-)
