Okay it make sense.  Thanks.
Few more questions about link between datastore and journal.
I understand that because each objectId has an activityId, it's easy for
the journal to display the related activity for each datastore entry. Right
? But what if an activity create extra datastore entries ? Is there also
the activtyId field in these extra datastore entries ? If yes, how avoiding
display it in the journal ? Guess also that each datastore entry has a date
time entry ?
