In this video discussed all about Mongo DB overview and Installation on Windows 10.

Introduction:

MongoDB is an open-source document database and leading NoSQL database. MongoDB is written in C++. This tutorial will give you great understanding on MongoDB concepts needed to create and deploy a highly scalable and performance-oriented database.

Audience:

Targeted audience designed for this course is Software Professionals who are willing to learn MongoDB Database in simple and easy steps. It will throw light on MongoDB concepts and after completing this course you will be at an intermediate level of expertise, from where you can take yourself at higher level of expertise.

Pre-Requisites:

Before proceeding with this tutorial, you should have a basic understanding of database, text editor and execution of programs, etc. Because we are going to develop high performance database, so it will be good if you have an understanding on the basic concepts of Database (RDBMS).

MongoDB – Overview:

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

Database

Database is a physical container for collections. Each database gets its own set of files on the file system. A single MongoDB server typically has multiple databases.

Collection

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 purpose.

Document

A 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.

MongoDB – Advantages:

 Any relational database has a typical schema design that shows number of tables and the relationship between these tables. While in MongoDB, there is no concept of relationship.

Advantages of MongoDB over RDBMS:

Schema less − MongoDB is a document database in which one collection holds different documents. Number of fields, content and size of the document can differ from one document to another.

Structure of a single object is clear.

No complex joins.

Deep query-ability. MongoDB supports dynamic queries on documents using a document-based query language that's nearly as powerful as SQL.

Tuning.

Ease of scale-out − MongoDB is easy to scale.

Conversion/mapping of application objects to database objects not needed.

Uses internal memory for storing the (windowed) working set, enabling faster access of data.

Why to Use MongoDB?

Document Oriented Storage − Data is stored in the form of JSON style documents.

Index on any attribute

Replication and high availability

Auto-Sharding

Rich queries

Fast in-place updates

Professional support by MongoDB

Where to Use MongoDB?
