Cassandra supports clusters and spanning of multiple data centers [ 2 ] with ...
NoSQL. NoSQL (originally referring to "non- SQL " or "non-relational") [1] is an approach to database design that focuses on providing a mechanism for storage and retrieval of data that is modeled in means other than the tabular relations used in relational databases. Instead of the typical tabular structure of a relational database, NoSQL ...
Document-oriented databases are one of the main categories of NoSQL databases, and the popularity of the term "document-oriented database" has grown [2] with the use of the term NoSQL itself. XML databases are a subclass of document-oriented databases that are optimized to work with XML documents. Graph databases are similar, but add another ...

According to computer scientist Eric Brewer of the University of California, Berkeley, the theorem first appeared in autumn 1998. [10] It was published as the CAP principle in 1999 [11] and presented as a conjecture by Brewer at the 2000 Symposium on Principles of Distributed Computing (PODC). [12]
Keyspace (distributed data store) A keyspace example with a number of column families. A keyspace (or key space) in a NoSQL data store is an object that holds together all column families of a design. [1][2] It is the outermost grouping of the data in the data store. [3] It resembles the schema concept in Relational database management systems. [4]
