It explains what is MongDB and it's features in simple words.

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
