NoSQL, generally refers to non-relational databases. With the rise of Internet web2.0 websites, traditional relational databases have been unable to cope with web2.0 websites, especially the super-large-scale and high-concurrency SNS-type web2.0 pure dynamic websites, which have exposed many insurmountable problems. The non-relational database has been developed very rapidly due to its own characteristics. NoSQL database was created to solve the challenges brought by multiple data types in large-scale data collections, especially big data application problems.
