MongoDB is a database based on distributed file storage. Written in C++ language. Designed to provide scalable, high-performance data storage solutions for WEB applications.
MongoDB is a product between relational and non-relational databases, and is the most function-rich and relational database among non-relational databases. It supports a very loose data structure in a JSON-like BSON format, so it can store more complex data types. The biggest feature of Mongo is that the query language it supports is very powerful, and its syntax is somewhat similar to an object-oriented query language, which can implement almost most of the functions of relational database single-table queries, and also supports indexing data.
