Java MongoDB Tutorial

In this tutorial, we will learn how to use MongoDB with Java programming language.

MongoDB is a cross-platform, document-oriented database that provides, high performance, high availability, and easy scalability. MongoDB works on the concept of collections and documents.

Before getting started with the Java MongoDB tutorial, let's first familiar with few MongoDB basic concepts like database, collection, and document.


A database is an organized collection of structured information, or data, typically stored electronically in a computer system. A database is usually controlled by a database management system (DBMS). 


A collection is a group of MongoDB documents. It is the equivalent of an RDBMS table. A collection exists within a single database. Collections do not enforce a schema. Documents within a collection can have different fields. Typically, all documents in a collection are of similar or related purposes.


A document is a set of key-value pairs. Documents have a dynamic schema. Dynamic schema means that documents in the same collection do not need to have the same set of fields or structures, and common fields in a collection's documents may hold different types of data.

Mapping Relational Database to MongoDB - Summary

Collections in MongoDB are equivalent to the tables in RDBMS.
Documents in MongoDB are equivalent to the rows in RDBMS.
Fields in MongoDB are equivalent to the columns in RDBMS.
Fields (key and value pairs) are stored in a document, documents are stored in collection and collections are stored in a database.
