Aggregation in NoSQL Databases

COUNT(*)? SUM(*)? AVG(*)? Working with non-relational (NoSQL) databases requires learning new methods for performing basic data aggregation. This talk explores the real-time aggregation options available in two popular document databases: Couchbase and MongoDB.

Couchbase’s map-reduce will be covered, along with MongoDB’s aggregation framework. Designing a schema for aggregation will also be part of the discussion. Some experience with a document database is expected.
