MongoDB is a product between a relational database and a non-relational database. It is the most feature-rich among non-relational databases and is most similar to a relational database. The data structure it supports is very loose and is a bson format similar to json, 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 an object-oriented query language. It can almost implement most functions similar to single-table queries in relational databases, and it also supports indexing of data.
Course Introduction: MongoDB is written in C language and is an open source database system based on distributed file storage. Under high load conditions, adding more nodes can ensure server performance. MongoDB aims to provide scalable, high-performance data storage solutions for WEB applications. "曰八mongodb Video Tutorial" will tell you how to use this distributed file storage database.
