All too often, a senior manager will get a

The platform should be the last thing determined; NOT the first.
RULE 1: Determine the application need
RULE 2: Keep the data as close to the application as possible
RULE 3: Determine Network/Security needs
RULE 4: Decide platform

RULE #2: I am not sure I agree with you on this one. Most of the time
it is the case but there are times I do not think it is wise(or
useful). There are other cases that it serves no purpose to keep the
data as close to the applications as possible. Example: The number of
people going through a turn style at say a Subway station. The
application (chances are) is at either another subway station or at a
railroad yard or some other place. There is no need to keep the data
at a subway station that I can think of the data is (are) only
useable for longer term number crunching. I would think that (going
by your rules) would be kept at each say subway station and then
(perhaps) polled hourly or a few times a day to another location. The
data is (IMO) no use by the station and at best might indicate
heavier than average traffic. This does the local station little or
no use. As one can plainly see that there are more people using the
station more than lets say either a hour ago or a week a go (assuming
you were there). This is a simple example (I think) muddies the water
in #2.
There are probably other examples that IMO blurs the #2 rule but I
want to keep this short. *IF* this needs to be real time numbers then
I disagree (my example is not needed for real time I would guess but
say it is) then data must be transmitted in real time to the
application so I guess the word "close" is somewhat relative and
sort of misleading.
This discussion does not talk about platform what so ever so I am not
pointing fingers (other than to say its not practical to put a MF in
a subway station).
