NOSQL is a database movement which began in early to mid 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, Dynamite, HBase, Hypertable, CouchDB, and MongoDB. Currently there is a New York NOSQL Meetup planned for October 5th, 2009 and a multi-day conference called NoSQL East being held October 28-30th 2009 in Atlanta, GA
