This document provides an overview of MongoDB, including: - MongoDB is a non-SQL, document-oriented database that provides high performance, high availability, and easy scalability. - In MongoDB, databases contain collections of documents rather than tables of rows. Documents can contain different fields and are equivalent to rows in a SQL database. - Some key advantages of MongoDB over SQL databases include its schemaless nature, ease of horizontal scaling, and rich query capabilities.

3. ∗ MongoDB is a No SQL database.
∗ 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.
∗ It is written in C++.
What is MongoDB?

4. ∗ 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.
Database

5. ∗ Collection is a group of MongoDB documents.
∗ It is the equivalent of an RDBMS table.
∗ A collection exists within a single database.
∗ Documents within a collection can have different
fields.
∗ Typically, all documents in a collection are of similar
or related purpose.
Collection

6. ∗ Documents exist inside a collection.
∗ Documentation can almost be thought of as rows in a
sql database, except they have key difference:
∗ Documents are schema-less
∗ Document used JSON Syntax
∗ The maximum size of a document is 16 megabytes
∗ Not Relational
Document

7. MongoDB SQL
database database
collection table
document record (row)
field column
embedded documents join
primary key (Default key _id provided
by mongodb itself)
primary key (user designated)
Index index
MongoDB to SQL Terminology

8. ∗ 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.
∗ Ease of scale-out
• Conversion/mapping of application objects to database
objects not needed.
Advantages of MongoDB over
RDBMS

9. ∗ Document Oriented Storage − Data is stored in the
form of JSON style documents.
∗ Index on any attribute
∗ Replication and high availability
∗ Rich queries
∗ Fast in-place updates
∗ Professional support by MongoDB
Why Use MongoDB?

10. ∗ Big Data
∗ Content Management and Delivery
∗ Mobile and Social Infrastructure
∗ User Data Management
∗ Data Hub
Where to Use MongoDB?

11. User of MongoDB

12. ∗ The use Command
• MongoDB use DATABASE_NAME is used to create database.
∗ Syntax
• use DATABASE_NAME
∗ Example
• use mydb
∗ To check your currently selected database
• Db
∗ To check your databases list
• show dbs
∗ To drop a existing database
• db.dropDatabase()
• This will delete the selected database
Create Database

13. ∗String
∗Integer
∗Boolean
∗Double
∗Min/Max key
∗Array
∗Timestamp
∗Object
∗Null
∗Date
∗Objecy ID
Datatypes

14. ∗ The createCollection() Method
• MongoDB db.createCollection(name, options) is used to
create collection.
∗ Syntax
• db.createCollection(name, options)
∗ Example
• db.createCollection(“student")
• db.createCollection("mycol", { capped : true, autoIndexId :
true, size : 6142800, max : 10000 } )
Create Collection

15. ∗ In MongoDB, you don't need to create collection.
∗ MongoDB creates collection automatically, when you
insert some document.
• db.stud.insert({"name" :”bhavesh"})
∗ db.collection.drop()
• db.stud.drop()
Continue…

16. ∗ To insert data into MongoDB collection, to use
MongoDB's insert() or save() method.
∗ Syntax
• db.COLLECTION_NAME.insert(document)
∗ Example
• db.student.insert({no:”115347”,name:”bhavesh”,address:{t
o:”ayavej”,taluka:”jesar”,dist:”Bhavnagar”,pin:”364510”}})
Insert Document

17. ∗ The find() Method
• To query data from MongoDB collection, you need to
use MongoDB's find()method.
∗ Example
• db.student.find()
∗ limit() Method
• db.student. find().limit(1)
Query Document

18. ∗ skip() method
• In MongoDB, skip() method is used to skip the document. It is
used with find() and limit() methods.
∗ Syntax
• db.COLLECTION_NAME.find().limit(NUMBER).skip(NUMBER)
∗ Example
• db.student.find().limit(1).skip(2)
∗ sort() method
• db.COLLECTION_NAME.find().sort({KEY:1})
• db.student.find().sort(“name”:-1)
Continue…

19. ∗ Update() method is used to update or modify the
existing documents of a collection.
∗ Syntax:
• db.COLLECTION_NAME.update(SELECTIOIN_CRITERIA,
UPDATED_DATA)
∗ Example
• db.student.find()
Update documents

20. ∗ db.student.update({name:”bhavesh”},{$set:{name:”b
havo”}})
∗ db.student.find()
Continue…

21. ∗ remove() method is used to remove a document from
the collection.
∗ Syntax
• db.COLLECTION_NAME.remove(DELLETION_CRITTERIA)
∗ Example
• db.student.remove({name:”bhavo”})
Delete Document
