This document provides an overview of MongoDB including what it is, how it compares to relational databases, how it achieves scalability through sharding, and how to perform basic operations like installation, startup/shutdown, data modeling, and CRUD operations. It also covers JSON data format, indexing, and backup utilities.

1. MongoDB ?

2. Agenda
 What is MongoDB?
 What is NOSQL?
 RDBMSVs NOSQL
 Scalability
 Sharding
 Installation MongoDB, Startup/Shutdown
 JSON
 Data Modeling
 CRUD
 Indexing
 Backup/Restore

3. MongoDB?
MongoDB is a Non-Relational, Document Oriented,
High Available, High Scalable, Schema-less,
BSON formatted supported, Sharding supported,
Open Source, NoSQL database.
It won’t support Joins and SQLs.
MongoDB named from humongous, meaning is
extremely large.

4. NO-SQL

5. RDBMSVs NOSQL

6. RDBMSVs NOSQL

7. Scalability
 Scalability means, system should support
increasing workloads.

8. RDBMS Scalability
(Vertical/ScaleUp)

9. NOSQL Scalability
(Horizontal/ScaleOut)

10. Sharding

11. Sharding: Sharing a large collection across multiple servers.

12. MongoDB Features

13. MongoDB Installation

14. Startup/Shutdown
 Mongod - server startup
 Mongo - client connection
 Exit - shut-down
Mongod –version
Mongod –help

15. Startup/Shutdown
mongod --dbpath c:mongodbdata
journal - redo directory, flash recovery
ns - namespace - system catalog
mongo --nodb
2+(3*6)
x={name:'sasi',age:32}
x.name
x.age

16. JSON
 Formats:
{ }
{
id:123,
name:'jk‘
}
{
id:123,
name:'jk',
hobbies:['cricket','movies']
}
{
id:123,
name:'jk',
hobbies:['cricket','movies'],
address:{add1:'line1',add2:'street1',city:'hyd'}
}

17. Data Modeling
 Mongo can host a no/of Databases.
 A Database holds a set of Collections.
 A Collection holds a set of Documents.
 A Document is a set of Key-Value pair.
 A Document is a Dynamic Schema.
 MongoDB is a JavaScript interpretor.
javascript ex:
for ( i=0; i<5; i++) print("Welcome to MongoDB");
 MongoDB stores data in BSON format
- BSON is in serialized format

18. CRUD Operations
SQL Mongo
Create Insert Insert
Read Select Find
Update Update Update
Delete Delete Remove

19. Indexing
 Indexes provide high performance read
operations for frequently used queries.

20. Backup Utilities
mongodump - take the dump of the database instance, it will store
dump in bson format.
mongorestore - restore the dump of the database instance, it will restore
bson dump only.
bsondump - the bsondump converts BSON files into human-readable
formats.
mongoexport - mongoexport is a utility that produces a JSON or CSV
export of data stored in a MongoDB instance
mongoimport - The mongoimport tool provides a route to import
content from a JSON, CSV, or TSV export created by mongoexport
