Yes.

I do not really want to "discuss" this problem "away" - data loss is a
serious thing. The differences in perception might just be about how
often it is really encountered in "real life".
There are two arguments I could bring which I think slightly relax the
situation for practical use (which might be considered lame from a
theoretical point of view):
1) There's a "auto-save backup files" functionality, which by default
saves a current snapshot every 15 minutes. This should also include your
recent manipulations to the DB, even if they're not yet part of the .odb.
2) OOo shouldn't crash too often :-\ Wasn't stability one of the goals
for 2.0 ...?

Anyway, in general you're right and this is a problem. I submitted issue
55274 to track this - feel free to add your comments.

I will take this discussion as inducement to think about concepts how we
can relax the problem for 2.0.1 (we might not be able to completely fix
it in this time frame). In general, this would be about defining more
situations where the DB content is synced into the .odt file. Currently,
it's "the last connection dies" and "OOo terminates properly" - which,
as you outlined, might be too seldom.

I am aware of the fact that this is a workaround only. Normally, you
would expect from a database that when you write a record, and unplug
your machine afterwards, that the data is still preserved and present in
the next run. Admittedly, this will be difficult to reach with 2.0.x :-\

Thanks & Ciao
Frank
