how different are the optimizers between the different commercial databases?
Will a query written one way from one vendor not run as well under a
different vendor?
Also, Im familiar with Oracle and I know that physical I/Os are generally
not considered much of a problem(its a small piece of the pie). Typical you
focus on decreasing logical I/Os. I am reading an academic database book
that states that physical I/Os are extremeley important. Is this the case
with databases created by other vendors?
