MongoDB and aggregation/merging

Greetings!

I will be posting about it later today but wanted to draw your attention to:

Hacking Chess with the MongoDB Pipeline

http://www.snailinaturtleneck.com/blog/2012/01/26/hacking-chess-with-the-mongodb-pipeline/

By Kristina Chodorow.

Kristina uses the new aggregation facilities of MongoDB to analyze chess 
games.

Aggregation is based upon uniform identifiers (chess pieces/moves) but 
the important point is that the analysis she presents isn't possible in 
the absence of aggregation (actual or simply keeping a mental tally).

I was thinking the what analysis is/is not possible in the absence of 
aggregation might be a fruitful topic of discussion.

Hope everyone is having a great week!

Patrick
