What is MongoDB and how to install MongoDB?

"MongoDB is an open-source document database that provides high performance, high availability, and easy scalability. Documents (objects) map nicely to programming language data types. Embedded documents and arrays reduce need for joins."

Other words:

"A MongoDB deployment hosts a number of databases. database holds a set of collections. collection holds a set of documents.document is a set of key-value pairs. Documents have dynamic schema. Dynamic schema means that documents in the same collection do not need to have the same set of fields or structure, and common fields in a collection’s documents may hold different types of data."

Document Database

A record in MongoDB is a document, which is a data structure composed of field (Key) and value pairs. MongoDB documents are similar to JSON objects. The values of fields may include other documents, arrays, and arrays of documents.A MongoDB document.

{

  "name":"Rossum",

  "age":54,

  "status":true,

  "groups":["news","sports"],

}

The advantages of using documents are:

• Documents (i.e. objects) correspond to native data types in many programming languages.

• Embedded documents and arrays reduce need for expensive joins.

• Dynamic schema supports fluent polymorphism.

• It is in document (Json) format, so there is no problem with join tables that’s why it’s speed is very fast rather then other database like Msql, Sqlserver and others.
