NoSQL分类

NoSQL数据库分类：

NoSQL DEFINITION:Next Generation Databases mostly addressing some of the points: beingnon-relational,distributed, open-source and horizontally scalable.

The original intention has been modern web-scale databases. The movement began early 2009 andis growing rapidly. Often more characteristics apply such as:schema-free,easy replication support, simple API, eventually consistent /BASE (not ACID), ahuge amount of data and more. So the misleading term"nosql" (the community nowtranslates it mostly with "not only sql") should be seen as an alias to something like thedefinition above.

Classification based on feature

Ben Scofield categorized NoSQL databases based on nonfunctional categories (“(il)ities“) plus a rating of their feature coverage:

Data Model	Performance	Scalability	Flexibility	Complexity	Functionality
Key-Value Stores	high	high	high	none	variable (none)
Column Store	high	high	moderate	low	minimal
Document Store	high	variable (high)	high	low	variable (low)
Graph Database	variable	variable	high	high	graph theory
Relational Database	variable	variable	low	moderate	relational algebra.
