Although the NoSQL movement does not bring fundamental technological changes to distributed data processing, it still leads to a deluge of research and practice on protocols and algorithms. In this article, I will make some systematic descriptions of the distributed features of the NoSQL database. The scalability of the system is the main reason to drive the development of the

In the past few years, relational databases have been the only choice for data persistence. Data workers only consider filtering these traditional databases, such as SQL Server, Oracle, or MySQL. You can even make some default options. For example, if you use. net, you generally select SQL server. If you use Java, you may prefer Oracle, Ruby is MySQL, and python is PostgreSQL or MySQL. The reason is simple: the robustness of relational databases has been proven in most applications for a long ti
