daytona was always a separate commercial product.
it was an extremely large, very efficient database.
you should think of it as analogous to a large postgres system.

for many years, probably now as well, it was the main way that
at&t stored per-call information. as of the mid 2000s, it had over 2 trillion
calls in it.
