NoSQL

NOSQL is a database movement which began in the spring of 2009. The term refers to certain non-relational data stores.

Trends in computer architectures are pressing databases in a direction that requires horizontal scalability. NOSQL attempts to address this requirement.

Google BigTable and Amazon Dynamo are NOSQL databases.

The San Francisco NOSQL Meetup on June 11, 2009 was important to the trend's development. Well over 100 software developers attended presentations of solutions such as Project Voldemort, Cassandra Project, Dynomite, HBase, Hypertable, CouchDB, and MongoDB.
