MongoDB is a database based on distributed file storage [1] written in C++ . Written in C++ language. It aims to provide scalable high-performance data storage solutions for WEB applications.
MongoDB is a product between relational databases and non-relational databases. It is the most feature-rich and most like relational databases among non-relational databases. The data structure it supports is very loose and is 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. Its syntax is somewhat similar to the object-oriented query language. It can almost realize most functions similar to single-table query in relational databases, and it also supports indexing of data .
Alibaba Cloud and mongoDB
Alibaba Cloud Database MongoDB has outstanding advantages in flexibility of deployment architecture, service availability, data reliability, security, and operation and maintenance costs.
