basic understanding:
MongoDB is a database based on distributed file storage. Written in C++ language. It aims to provide scalable high-performance data storage solutions for WEB applications.
MongoDB is one of the most popular Nosql databases out there.
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 bjson 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 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.
Learning Tutorial: MongoDB Database
(The course mainly explains the basic knowledge of MongoDB database, including MongoDB database installation, configuration, service startup, data CRUD operation function use, MongoDB index use (unique index, geographic index, expired index, full-text index, etc.), MapReduce operation Implementation, user management, Java operation support for MongoDB (complete explanation based on 2.x driver and 3.x driver). By learning this course, readers will have the ability to develop MongoDB database and be able to use MongoDB for project development. In addition This course will use the method of comparing the Oracle database with the MongoDB database to explain. If you are not familiar with the Oracle database, you can refer to the book "Oracle Development Practical Classics" for detailed study.)
