Mostly agreed.

The people who promote OO in c.d.t. nearly always write as if Bachman had won the great debate. The idea that it is possible to specify data without specifying the location of said data eludes them. The idea that it might be desirable to do so is just completely beyond their ken. If you miss these two points, there is no hope that you'll get the gist of RM, no matter how well you learn the rest of it.

The people who promote RM in c.d.t. usually write as if the advances in programming productivity that accompanied the gradual shift from structured programming to OO were of no interest or value whatsoever.

The two groups talk past each other. And the word "object" in the title is a real good indicator. Sigh! Received on Wed Mar 14 2007 - 06:59:41 CDT
