MongoDB MapReduce Stats Engine?

I'm not sure about my concept, it's just an idea.

I'm not sure about my concept, it's just an idea. Your two example datasets have common structure. Both contain documents with to properties: one has string value, second is an array.So your map-reduce should iterate over document properties and check the type of particular property.

Then agregate according to type and property name.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
