NoSQL databases get a lot of press coverage, but there seems to be a lot of confusion surrounding them, as in which situations they work better than a Relational Database, and how to choose one over another. This talk will give an overview of the NoSQL landscape and a classification for the different architectural categories, clarifying the base concepts and the terminology, and will provide a comparison of the features, the strengths and the drawbacks of the most popular projects (CouchDB, MongoDB, Riak, Redis, Membase, Neo4j, Cassandra, HBase, Hypertable).

    A very good talk, thanks Lorenzo. A couple of questions. How much data equates to ‘big data’? I’m using several TB’s with a traditional RDBMS. It seems subjective but is there a yard stick?

    And with regards to Graph DB’s, they sound to me like RDBMS’s as you are expressing relationships between nodes/entities and again are hard to scale horizontally.
