Well it is safe in general, but in this particular case opening table directly might be perhaps more practical.

Like Tore, I do NOT advice using DE, all I said that DE _can_ be used safely if need be.
95% of my forms do not use DE, but there are small numbers of forms that do, and do it for a good reason (of having Private DS)
It can be very well other way around, but that is matter of prefered design/architecture.
