Redis basic tutorial Section 2 introduction and Application scenarios of Redis and NoSql

NoSQL (NoSQL = Not Only SQL), which means "not just SQL", is a new revolutionary movement of database, and it was suggested in the early days that the trend was getting higher and higher in 2009. Proponents of NoSQL advocate the use of non-relational data storage, compared with the overwhelming use of relational databases, this concept is undoubtedly the injection of a new kind of thinking.

Characteristics of NoSQL:

Deal with a large amount of poor data

Running in a cheap PC server cluster

Address performance bottlenecks

NOSQL application scenarios:

Read and write data with high concurrency

Efficient storage and access to massive data

High scalability and high availability of data

Redis is an open source (BSD licensed), in-memory data structure store, used as database, cache and message broker. It supports data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs andgeospatial indexes with radius queries.
