Justin Dearing presents a brief introduction to MongoDB, and focuses on interacting with it in Mono via the official 10gen driver. Techniques for handling business logic in application code, such as LINQ are discussed. This is a very code centric talk.
Rick Bullotta and Emil Eifrem discuss how to use graph databases to model the real world, people, systems and things, talking advantage of the relationships between various data elements.
CouchDB is a schema-free document database. But now that the NoSQL movement is in full swing, there are several document databases to choose from, so why choose Couch? Two things really set CouchDB apart from the rest: its map/reduce views and its RESTful API. Since the API is RESTful, you can easily use Couch from any platform that can talk HTTP.
