History of MondoDB
 Till 1970 - Data Stored in Flat File Systems.
 Flat files-No standard structure, Search is biggest problem
 DBMS Database in Early 1980.
 E.F.Codd's rule for RDBMS in Early 1990.
 SQL is language to access database information.
 Problem with RDBMS is
 Data Volume is high, speed become slower.
 Various type of information in uniform structure is difficult to
manage.
 To overcome from this problems Document base database
is introduced as NoSQL database.

3. Databases can be divided in 3 types:
 RDBMS (Relational Database Management System)
 OLAP (Online Analytical Processing)
 NoSQL (recently developed database)

4. What is NoSQL Database
 NoSQL Database is used to refer a non-SQL or non
relational database.
 It provides a mechanism for storage and retrieval of
data other than tabular relations model used in
relational databases.
 NoSQL database doesn't use tables for storing data. It
is generally used to store big data and real-time web
applications.

5. Advantages of NoSQL
 Automatic Failover
 Horizontal Scaling - unlimited
 JSON support
 Expressive query language
 Simple to learn for developers
 Data as a code
 Fast performance.

6. What is MongoDB [1]
 Mongo DB is an Open source product by 10gen - is
free to use.
 MongoDB is a No SQL database.
 Mongo DB is a document-oriented database.
 NoSchema
 Single Object Structure
 JSON like BSON == Binary JSON
 No Complex Join

7. What is MongoDB [2]
 MongoDB stores data in flexible, JSON-like documents,
meaning fields can vary from document to document and data
 structure can be changed over time
 The document model maps to the objects in your application
code, making data easy to work with
 Ad hoc queries, indexing, and real time aggregation provide
powerful ways to access and analyze your data
 MongoDB is a distributed database at its core, so high
availability, horizontal scaling, and geographic distribution are
built in and easy to use

8. Term Comparisons with RDBMS
 Document = Record
 Collection = Table
 Container = Database
 Field = column (key : value pair)
SESSION:01

9. Document Structure
 Example:
{
_id: 563479cc8a8a4246bd27d784,
customer_id: 11,
customer_name: Smith Taylor,
order_date: 20-Jun-2021
}
key component is : _id : object id
automatically assign by database
24 digits alpha-numeric
SESSION:01

10. Data Type Supports
 String
 Integer
 Boolean
 Double
 Min/Max key
 Arrays
 Object
 Null
 Symbol
 Date

11. Download and Install MongoDB
 http://www.mongodb.org/downloads (Register
and then donwload)
 https://www.mongodb.com/try/download/commu
nity (Free trial version)
 Default port of MongoDB server is 27017
 connection : https://localhost:27017
SESSION:01

12. Start MongoDB
 JavaScript Driver : bin folder -> mongo.exe
 it will prompt for javascript prompt >
 write a sample javascript code i.e.
 > var name="Jainul"
 > print("My Name: ",name);
My Name: Jainul <<--- OUTPUT
 >
SESSION:01

13. Use GUI MongoDB
 Use MongoDB GUI by installing MongoDB Compass
 It will install "mongodb-compass...exe" in bin
folder
 It will run and provide GUI interface to interact
with database
 You can use Robo 3T / Studio 3T a GUI for
https://robomongo.org/

14. Connecting MongoDB with front end
 --------JavaScript code for connection ------------
 import { MongoClient } from 'mongodb'
 export async function connect () {
 // Connection URL
 const url = 'mongodb://localhost:27017/my_database'
 let db
 try {
 db = await MongoClient.connect(url)
 console.log('Connected successfully!')
 } catch (err) {
 // Handle error
 }
 return db
 }
SESSION:01

15. Connecting MongoDB with front end
 ============ C# connectivity =============
 var client = new MongoClient();
 var database = client.GetDatabase("test");
 var collection =
database.GetCollection("restaurants");
