• Tim,

    As a IT practitioner I am sure that you understand that common terminology is essential in maintaining clarity. It is a good article as an introduction to the technique for programmers with the caveats previously posted. I hope you took the constructive input as such. Some phrasing is occasionally harsh but usually it is not intended as such on these forums.
