Introduction to mongodb:

MongoDB is a product between relational database and non-relational database, which is the most functional and most like relational database in non-relational database. The data structure he supports is very loose, which is similar to json's bjson format, so it can store more complex data types. The most important feature of Mongo is that the query language it supports is very powerful, and its syntax is somewhat similar to the object-oriented query language. It can almost achieve most of the functions similar to the single table query of relational database, and also supports the establishment of data indexing.
