NoSQL数据库分类：
-
NoSQL DEFINITION: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. 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),a
huge 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.
