It is about access rights: if you want your changes safe, don't allow
others to edit your files. That's that, and it's *COMPLETELY* *CLEAR*
even for my granny (when explained on a simile that anybody can
rubber out your writing if you let him to play with the paper on
which you wrote that).
(I believe Ondra actually wrote that)
Michael continues:
I respectfully disagree. I think it depends on the application. If
you're writing a database, for instance, then standard procedure,
AFAIK, is that you get exclusive access to the record you're currently
editing, but that any number of people can edit the database at any
one time.
Writing a "database" never seemed to be an issue in the first place.
From the first message in this thread I got the impression Donald was
talking about a document based application, an application dealing with
single files. If this is the case I agree with Ondra and would suggest
using some kind of versioning system.
Perhaps you got another impression from Donald's initial message.
But this doesn't matter as Donald hasn't been very clear on why "this
is bad". Just stating that "this is bad" isn't a good enough problem
description. Donald could explain in more detail his application, how
it works and in what situations this "bad" behaviour poses a problem.
- He could describe why several users would want to save to the same
file at the same time.
- He could explain why his application, with knowledge of the above,
still preferrs a "single plain file" solution.
Until then we can't give a good answer, only speculate.
Just a few thoughts,
Malte
