Okay, so you are doing the technical analysis for now.

However, doing a technical analysis correctly does not mean to blindly
ask about all the advanced features for each subsystem. The technical
analysis is part of the entire evaluation process. That process starts
with collecting the business requirements and continues with specifying
the technical requirements based on that. Not the other way round,
because technology should not drive, it should serve (unless the
technology in question is your business).

Possible changes in business model might slightly change the technical
requirements in the future, so an appropriate security margin is added.
But the attempt to build canned technical analysis for later reuse is
what leads to the worst solutions. How good is a decision based on 2
year old technical information?

Now all the possible candidates get compared against these
"requirements". That candidate "O" has the super duper buzzword feature
"XYZ" candidate "P" does not have is of very little importance unless
"XYZ" is somewhere on the requirements list. The availability of that
extra feature will not result in any gain here.

In an earlier eMail you pointed out that 2 phase commit is essential for
SMP/distributed applications. I know well what a distributed application
is, but what in the world is an SMP application?
