I just drop a single transaction component on datamodule (
for each connection as some times I am using more than on
database ). The default transaction ( and there is only one
for all queries ) is then replaced by the one I have added.
Then I run the isolation 'tiCommitted' and AutoCommit.

It sounds as if that is the way you want to work - and that
is how the default transaction is configured anyway.

I get confused here myself, as if the commit is happening
Automatically then you sound not even need to use
CommitRetaining, it happens automagiclly - but I seem to
need to use it sometimes, probably because I am not using
the 'real' default transaction.

Only add code or components if you want to take control of
something, so you should be OK with just opening and closing
as required.
