Mongo introduction
MongoDB is a product between relational database and non-relational database. Among non-relational databases, it has the most rich functions and is the most like relational database. The data structure it supports is very loose, in jSON-like Bson format, so it can store more complex data classes. The biggest feature of Mongo is that the query language it supports is very powerful. Its syntax is somewhat similar to object-oriented query language. It can almost achieve most of the functions similar to single table query of relational database, and it also supports data indexing. It is characterized by high performance, easy deployment, easy use, and very convenient data storage.
