Aggregation in MongoDB (Part 1) by Rick Copeland.

From the post:

In some previous posts on mongodb and python,
pymongo, and gridfs, I introduced the NoSQL database MongoDB how to use it from Python, and how to use it to store large (more than 16 MB) files in it. Here, I’ll be showing you a few of the features that the current (2.0) version of MongoDB includes for performing aggregation. In a future post, I’ll give you a peek into the new aggregation framework included in MongoDB version 2.1.

An index “aggregates” information about a subject (called an ‘entry’), where the information is traditionally found between the covers of a book.

MongoDB offers predefined as well as custom “aggregations,” where the information field can be larger than a single book.

Good introduction to aggregation in MongoDB, although you (and I) really should get around to reading the MondoDB documentation.
