MongoDB is an open source database management system (DBMS) that uses a document-oriented database model that supports numerous kinds of data. Rather than using tables and rows as in relational databases, the MongoDB architecture is formed of collections and documents. MongoDB stores data in JSON-like documents that can vary in structure.

Is MongoDB a NoSQL?

Yes MongoDB is a NoSQL meaning that you can create records without first defining the structure, such as the fields or the types of their values. You can change the structure of records (which we call documents) simply by adding new fields or deleting existing ones.
Example:
MySQL needs a column defined and declared while inserting data:
INSERT INTO users (user_id, age, status)VALUES ('bcd001', 45, 'A')

While MongoDB does not need columns or fields while insertion.

db.users.insert({ user_id: 'bcd001', age: 45, status: 'A'})
- OR-
db.users.insert({ user_id: 'bcd001', age: 45, name:'Decodeweb'})

Many ideas in MySQL have close analogs in MongoDB. This table outlines a number of common ideas in every system.

What is the use of MongoDB?

Majorly, MongoDB is used where the database schema is not fixed and senstive information is not required to store, some of the areas where MongoDB is preferred are:

1. E-commerce product catalog.
2. Blogs and content management.
3. Real-time analytics and high-speed logging, caching, and high scalability.
4. Configuration management.
5. Maintaining location-based data — Geospatial data.
6. Mobile and social networking sites.
7. Evolving data requirements.
8. Loosely coupled objectives — the design may change over time.

AdhaUIDAI uses MongoDB

Adhar is a superb example of real world use cases of MongoDB. India’s unique Identification project, also known as Aadhar, is the world’s biggest biometrics information holder. Aadhar is targeted to capture demographic and biometric information of over 1.2 billion residents.
Aadhar has used MongoDB jointly with other databases to store this large quantity of information. MongoDB was among many database providers, apart from MySQL, Hadoop and HBase, originally implemented for running the database search. Here, MySQL is employed for storing demographic information and MongoDB is employed to store pictures. As per techcrunch.com, MongoDB has nothing to do with the “sensitive” information.

Is MongoDB better than MySQL or any other RDBMS?

The typical schema of a relational database (e.g. MySQL) shows the amount of tables and also the relationship between the tables, however MongoDB doesn't follow the idea of relationship.
Go through the following table to know how precisely an expert NoSQL database like MongoDB differs from RDBMS. This table has shown 9 totally different comparisons between the two.
MongoDB
RDBM
Document-oriented and non-relational database.
Relational database.
Document based.
Row based.
Field based.
Column based
Collection based and key–value pair.
Table based
Gives JavaScript client for querying.
Does not Give JavaScript client for querying,e.g. Robo3T
Relatively easy to set up.
Comparatively not that easy to set up.
No SQL injection vulnerability.
Quite vulnerable to SQL injection.
Has dynamic schema and ideal for hierarchical data storage.
Has predefined schema and not good for hierarchical data storage
100 times faster and horizontally scalable through sharding.
By increasing RAM, vertical scaling can happen

Is MongoDB free for commercial use?

Initially MongoDB was licensed under Free software Foundation’s gnu AGPL v3.0
Which means that :

1. You could access the source code and make changes that you just need for business requirements.
2. Distribute free copies of the software ( additionally charge if you're feeling like doing it)
3. Client application that used the database could be a separate work

But it is not free any more since the introduction of SSPL (Server Side Public License) that disallows running software as-a-service if it's not open source. This gives Cassandra an edge over MongoDB when it comes to a completely free-to-use NoSQL database
You can read more about MongoDB SSPL here.

Where to download MongoDB from ?

MongoDB server for local development can be downloaded from MongoDB Community Version and the GUI tool to access server can be downloaded from Robomongo.org

How to install MongoDB in windows, ubuntu, mac ?

Windows: Follow this post as this shows a straightforward way to install MongoDB on Windows.

Ubuntu:

Step 1: Import the MongoDB repository

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10
Create a source list file for MongoDB
echo "deb http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.4 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.4.list
Update the local package repository
sudo apt-get update

Step 2: Install the MongoDB packages

Install the latest stable version of MongoDB:
sudo apt-get install -y mongodb-org
Install a specific release of MongoDB:
You must specify each component package specifically with their version number, check the following example:
sudo apt-get install -y mongodb-org=3.4 mongodb-org-server=3.4 mongodb-org-shell=3.4 mongodb-org-mongos=3.4 mongodb-org-tools=3.4

Step 3: Launch MongoDB as a service on Ubuntu 16.04

We need to create a unit file, which tells systemd how to manage a resource. Most common unit type, service, determine how to start or stop the service, auto-start etc.
Create a configuration file named mongodb.service in /etc/systemd/system to manage the MongoDB service.
sudo vim /etc/systemd/system/mongodb.service
Copy the following contents in the file.
#Unit contains the dependencies to be satisfied before the service is started. [Unit] Description=MongoDB Database After=network.target Documentation=https://docs.mongodb.org/manual # Service tells systemd, how the service should be started. # Key `User` specifies that the server will run under the mongodb user and # `ExecStart` defines the startup command for MongoDB server. [Service] User=mongodb Group=mongodb ExecStart=/usbin/mongod --quiet --config /etc/mongod.conf # Install tells systemd when the service should be automatically started. # `multi-user.target` means the server will be automatically started during boot. [Install] WantedBy=multi-user.target
Update the systemd service with the command stated below:
systemctl daemon-reload
Start the service with systemcl.
sudo systemctl start mongodb
Check if mongodb has been started on port 27017 with netstat command:
netstat -plntu
Check if the service has started properly.
sudo systemctl status mongodb
The output to the above command will show `active (running)` status with the PID and Memory/CPU it is consuming.
Enable auto start MongoDB when system starts.
sudo systemctl enable mongodb
Stop MongoDB
sudo systemctl stop mongodb
Restart MongoDB
sudo systemctl restart mongodb

Step 4: Configure and Connect MongoDB

Open MongoDB shell on your server by typing below command:
mongo
Switch to the database admin
use admin
Create the root user
db.createUser({user:"admin", pwd:"password", roles:[{role:"root", db:"admin"}]})
Connect MongoDB
Restart MongoDB( command mentioned above ) and connect with user created with this command:
mongo -u admin -p admin123 --authenticationDatabase admin
You can see the mongo connecting. Check the databases using the following command:
Show dbs

Mac:

Step 1. Open the Terminal app and type:

brew update

Step 2. After updating Homebrew.

brew install mongodb

Step 3. Create directory.

After downloading Mongo, create the “db” directory. This is where the Mongo data files will live. You can create the directory in the default location by running mkdir -p /data/db
Make sure that the /data/db directory has the right permissions by running
sudo chown -R `id -un` /data/db # Enter your password

Step 4. Run MongoDB

Run the Mongo daemon, in one of your terminal windows run
mongod
This should start the Mongo server.
Step 5. Run Mongo Shell
Run the Mongo shell, with the Mongo daemon running in one terminal, type
mongo
in another terminal window. This will run the Mongo shell which is an application to access data in MongoDB.
Step 6. To exit the Mongo shell
quit()
Step 7. To stop the Mongo daemon
ctrl-c
