NOSQL, the full name is not-only Sql, refers to the non-relational database. The next generation of databases mainly solves several key points: non-relational, distributed, open-source, horizontally extensible. The original goal was for large-scale Web applications, which began in the early 2009 with features such as freedom of mode, support for simple replication, simple APIs, eventual consistency (non-acid), high-capacity data, and so on. NoSQL is the most used when the number of key-value storage, of course, there are other document-type, column storage, graph database, XML database and so on.
