Thank you, again

So interesting

Before I knew about what data in MongoDB looked like, I looked at a complex structure of hashes and arrays and thought, if one could set up a structure and had a way of inserting data into it easily, then it would be a visibly useful way of storing data. Low and behold, it seems to be the case.

Not that I have any knowledge or ability concerning MongoDB, hashes, or other stuff like them.

That's how I started looking at Mongo a few weeks ago. It's fascinating. I've taught myself a little sql. I'm looking for a reason to adapt my sql data to use it in Mongo, but I can't at present see any valid reason for doing that. Pity.

Thank you very much for your help with this.

I understand:

and your data structure examples, and manipulating them, better now.
