   RE: [xml-dev] Another strong/loose decision tree node (was Re: [xml-dev]

That's why they hire consultants and we have spouses: so someone can 
tell us what we want. :-)

In the 1980sCE (CALS Era), we called it an "Automated Information System" or 
AIS for short.  It divided the world into an Enterprise Database (everyone 
can access it: the shared data) and Workgroup dbs (functional areas).  It all 
looked very spiffy on paper.  Of course, tech at the time wasn't up to it, but 
it generated a lot of papers.  Now we know that any decent relational database 
with modules that can be turned on and off depending on the group privileges 
works pretty much like that.  We can always add tables but renormalizing 
after the fact is very painful.

So just change the terminology, nod and say, "yes we do AIS" so the 
consultant will appear as if they really do have a new vision when 
in fact, the same system will ship, the implementation personnel will 
configure it for local conditions, and everyone will be happy.

A lot depends on the axis from custom one-off work to shrinkwrap.

Ooh, there's that too. I try to make my intial design as modular and
extensible as possible to counter this kind of stuff (and later
development benefits from this too), but there's always some design change
that needs to be made later down the line, definitely.

Bloody clients. Never know what they want...
