Thank you very much erichansen1836 for providing your example.

As you wrote, i requested it. So i take up this challenge and i hope very much that i don't make a fool of myself (because i'm really no database expert):

"Random access lookup is instantaneous !!! FAST!"

Very nice - if so. But unfortunately i can't verify/reproduce this because i don't have any data for benchmarking.

And traditionally this effort is left to the author.

I've been reading your code over and over again but i can't see any benefit for the moment.

But as you may have noticed, i rely very much on my intuition. Some might say i guess sometimes.

So i guess that it would be perhaps a good idea to read a bit about Star schema and all the related stuff you may find.

Just an idea - and i hope it isn't misleading.

Best regards, Karl
