No. It is a completely separate development
starting from work on databases in the
AXE 10 world.

In a big company there are always lots of
separate independent developments going on.
Occasionally management jumps in and tries
to coordinate and the effect is more like
when a human mucks around with a stick in
an ant-heap.

The NDB development did not start by somebody
trying to solve a database problem and then
looked at different possible solutions. It
started by somebody doing a PhD thesis in the
database field and then got some innovation
capital to try to market it.

Merry Christmas and a Prosperous New Year
to all Erlang fans !
