Maybe so...  However before moving in that direction, it's best to be
sure the methodology is right -- something that shell scripts do well!

The Transaction capabilities provide database reliability and greatly
reduce the likelihood of corruption.  That's their "up" side.  The
"down" side is the additional file storage needed and the complexity of
dealing with the several files involved.
