What is NoSQL? NoSQL describes a family of approaches to managing data at an enterprise level that have key similarities, but - at the same time - are very different from classic SQL based relational databases.
NoSQL has emerged as a 'movement' over the last 5 years and many specific noSQL datastores - Mongo, Redis, HBase, Cassandra, Neo4J - are being used for mission critical systems by many organizations including Facebook, LinkedIn, Dropbox, American Express, NSA, & the CIA. Does NoSQL spell the end of SQL based relational datastores like Oracle, MySQL, SQLServer, & Sybase? Definitely not, but the world is moving in the direction of "Polyglot Persistence" and away from the "Relational Persistence" hegemony. In my presentation I will explain why this shift is occurring and will speculate about what the future will hold.
