SQL VS NoSQL
• NoSQL (often interpreted as Not only SQL) database
• It provides a mechanism for storage and retrieval of data that is modeled
in means other than the tabular relations used in relational databases.
SQL NoSQL
Relational Database Management System (RDBMS) Non-relational or distributed database system.
These databases have fixed or static or predefined schema They have dynamic schema
These databases are best suited for complex queries These databases are not so good for complex queries
Vertically Scalable Horizontally scalable
Follows ACID property Follows BASE property

SQL VS NoSQL
• ACID Properties:
1. Atomicity; The entire transaction
takes place at once or doesn't
happen at all
2. Consistency; The database is
consistent before and after the
transaction
3. Isolation; Multiple transactions
occur independently without
interference
4. Durability; The changes of
successful transaction occurs even if
the systems failure occurs

Atomicity Consistency

SQL VS NoSQL
• CAP Properties:
1. Consistency; that the nodes will have
the same copies of a replicated data
item visible for various transactions
2. Availability; that each read or write
request for a data item will either be
processed successfully or will receive a
message that the operation cannot be
completed
3. Partition tolerance; the system can
continue operating even if the
network connecting the nodes has a
fault that results in two or more
partitions, where the nodes in each
partition can only communicate
among each other.

What is MongoDB ?
A database management
system designed to
rapidly develop web
applications and internet
infrastructure.
A general-purpose
document database
designed for modern
application development
and for the cloud.
A good NoSQL document
database with a range of
features that, in the
open-source NoSQL
world, are hard to beat.

What is MongoDB ?
Database Collections
MongoDB stores data
as JSON/BSON (Binary
JSON) documents
In MongoDB, a
collection is a group of
documents

MongoDB Data Types
• String
This is the most commonly used datatype to store the data. String in MongoDB must be
UTF-8 valid.
• Integer
This type is used to store a numerical value. Integer can be 32 bit or 64 bit depending
upon your server.
• Double
This type is used to store floating point values.
• Date
This datatype is used to store the current date or time in UNIX time format. You can
specify your own date time by creating object of Date and passing day, month, year
into it.
• Boolean
This type is used to store a boolean (true/ false) value.

MongoDB Data Types
• Object ID
This datatype is used to store the document’s ID.
• Array
This type is used to store arrays or list or multiple values into one key.
• Timestamp
ctimestamp. This can be handy for recording when a document has been modified or
added.
• Code
This datatype is used to store JavaScript code into the document.
• Regular Expression
This datatype is used to store regular expression.

Installation MongoDB on Windows

Installation on Windows
• Step 1: Go to MongoDB download Page
and click download as shown in the
screenshot. A .msi file like this
mongodb-win32-x86_64-2008plus-ssl-
3.4.7-signed will be downloaded in
your system. Double click on the file to
run the installer.

• Step 2: Click Run when the MongoDB
installation windows pops up.

• Step 3: Click Next when the MongoDB
installation windows pops up.

• Step 4: Accept the MongoDB user
Agreement and click Next.

• Step 5: When the setup asks you to
choose the Setup type, choose
Complete.

• Step 6: Click Next when the MongoDB
service configuration. MongoDB will be
installed in the windows service

• Step 7: Choose Install MongoDB
Compass if you want to use the
MongoDB User Interface, or ignore it
and continue by clicking Next in the
Install MongoDB Compass window

• Step 8: Click Install to begin the
installation.

MongoDB CRUD
CREATE DATABASE
MongoDB use DATABASE_NAME is used to create database. The command will create a
new database if it doesn't exist, otherwise it will return the existing database.

SQL Create Database
• SQL Server
CREATE DATABASE databasename;
Example: CREATE DATABASE testdb;
• MySQL
CREATE DATABASE databasename;
Example: CREATE DATABASE testdb;

MongoDB CRUD
INSERT DOCUMENT

SQL Insert Query
• SQL Server
 Single
INSERT INTO tablename (c1,c2,...)
VALUES (v11,v12,...);
 Multiple
VALUES (v11,v12,...), (v21,v22,...), ….. , (vnn,vn2,...);
• MySQL
 Single
VALUES (v11,v12,...);
 Multiple
