"NoSQL refers to a class of databases 1) are intended to perform at internet (Facebook, Twitter, LinkedIn) scale and 2) reject the relational model in favor of other (key-value, document, graph) models." -- http://www.greenhornconnect.com/blog/dan-croak-what-nosqlhttp://www.greenhornconnect.com/blog/dan-croak-what-nosql "Next Generation Databases mostly addressing some of the points: being non-relational, distributed, open-source and horizontally scalable. The original intention has been modern web-scale databases. … Often more characteristics apply as: schema-free, easy replication support, simple API, eventually consistent /BASE (not ACID), a huge data amount, and more." -- http://nosql-database.org/ http://nosql-database.org/ "NoSQL (sometimes expanded to "not only SQL") is a broad class of database management systems that differ from classic relational database management systems (RDBMSes)…. These data stores may not require fixed table schemas, usually avoid join operations, and typically scale horizontally." -- Wikipedia database management systemsrelational database management systemstable schemasjoinscale horizontallyWikipedia
