NOSQL Databases

The page presents NoSQL as an umbrella term for next-generation databases that are non-relational, distributed, open-source, and horizontally scalable. It also says the term is misleading and is now often expanded as “not only SQL”. Beyond the definition, the page serves as a large catalog of systems grouped by database model, along with events, forums, news feeds, concepts, and search or indexing links.
