[Tutor] ways to sync databases with Python and SQLite?

[Chad Crabtree]

One way to work around this and still use SQLight is to put the database on
a shared drive.  SQLight does table locking, or is it file locking.  Anyways
conflicts will be very minimal to non-existant with only two clients as most
operations will complete in microseconds.  The SQLight website even says
this is a fine practice.

However synchronizing two separeatly running databases is a very hard task,
and is very very easy to get wrong.

However if all that one does is read and does no updates or deletes then you
could just copy the database over to the 'client' user.
