How would you implement Valentina so that it could support some
degree of atomicity? That is to say a "transaction" that involves
two database operations where the second is dependent on the first;
if the second database operation fails, then the first one ought to
be backed out in order to return everything to its original state.
"Atomicity" treats the entire transaction as a unit.
I'm asking these questions about ACID and atomicity because while
it's possible to hack data checking and recovery with Valentina's
front-end (whatever front-end that might be), it really ought to be
done in the database itself. Is it possible that Valentina will
someday support this stuff?
Make sense?
