Install and uninstall Mongodb databases on centos 7
MongoDB is a distributed file storage-based database. Written in C ++. It is designed to provide scalable, high-performance data storage solutions for WEB applications. MongoDBMongoDB is a product between relational databases and non-relational databases. It features the most abundant and most like relational databases. The supported data structure is very loose and is similar to the json bson format, so it can store more complex data types. The biggest feature of Mongo is that it supports a very powerful query language. Its syntax is somewhat similar to an Object-Oriented Query Language. It can almost implement most of the functions similar to single-table queries in relational databases, it also supports data indexing. This document is summarized on the official website.1.
