I've been looking into NoSQL (particularily MangoDB) and am liking what I see. I have one clarification though:
If I'm gathering data about a particular "thing" on a daily basis, should I have one document per "thing" and add the new data to it every day? Or should I be creating a new document for each day's data?
I would prefer to expand the document with each days findings, but fear that this could have performance issues as the document could expand indefinitely. Or is this the point of NoSQL and am I stuck in a relational mindset??
