I hear that a lot, but
Hello,
Inorder to suit the needs of my embedded device, I have changed the location
of the .db-wal file from the location of the db file to tmpfs. Does sqlite
make assumptions(persistence etc) based on the location of the file ?

That isn't always the correct approach and requires clocks to be
synchronized - something that is

That is what makes these databases (variously document oriented or JSON) so
attractive. There is no rigid schema and no two documents need
Roger, thanks for good explanation and examples of the multi-master
replication problems.
But I think a conflict-resolutions strategies may be independent. And
checking logical data
integrity is needed for systems without replication too. This checking
is not a part of the
replication but it's

This is how I build which also works with grabbing the current development
snapshots. After extracting the relevant archive:

I can use Linux if it makes it easier, but I gather from the rest of your
mail that you still won't be able to help me. Thank you anyway for trying.

Any database system can be nonsensical. If you have multiple people editing
prices for the same item even with a single instance database you can have
the wrong final answer. But that is a procedural and business issue, not a
technological one.

Okay. So CouchDB requires intentional data entry and uses

I am using the amalgamation embedded in my program. I am a little unfamiliar
with configure / make as I have almost always used IDEs that handle these
things (I think). I don't know what the sqlite-autoconf-3070701.tar.gz file

You customers have edit privilegies to you prices?! It's not the
replication problem of cource.

Can you refer me to instructions on building the amalgamation? The SQLite
website only says something like "Download the source, hand edit the make
file, and run make". Very unhelpful as I don't know what to do with the make
