This document provides an overview of NoSQL databases by comparing them to SQL databases. It discusses how companies like Google and Facebook needed alternatives to SQL as their data grew tremendously. This led to the development of Google's BigTable database and Facebook's Cassandra. The document outlines some key benefits of NoSQL databases like elastic scaling, handling big data, reduced reliance on DBAs, and more flexible data models. It also compares NoSQL to SQL in areas like ACID properties, the CAP theorem, maturity, support, analytics capabilities, administration, and required expertise.

2. What is NoSQL
This does NOT mean “No SQL”

3. What is NoSQL
This does mean “Not ONLY SQL”

4. Why is Not only SQL
Google once ran off of 40,000 MySQL installations

5. Why is Not only SQL
Facebook was at one point spending $1M per month for specialized
database hardware to serve their pictures.

6. Why is Not only SQL
These unviable solutions led to a re-evaluation of existing database
technologies and led to the Not-Only-SQL (NoSQL) movement.

7. The rise of Not only SQL - 1
Google's Way

8. The rise of Not only SQL - 1
1. Google invented for BigTable database.

9. The rise of Not only SQL - 1
1. Google invented for BigTable database.
2. BigTable maps two arbitrary string values (row key and column key)
and timestamp (hence three dimensional mapping) into associated
arbitrary byte array.

10. The rise of Not only SQL - 1
1. Google invented for BigTable database.
2. BigTable maps two arbitrary string values (row key and column key)
and timestamp (hence three dimensional mapping) into associated
arbitrary byte array.
3. It is not a relational database and can be better defined as a sparse,
distributed multi-dimensional sorted map.

11. The rise of Not only SQL - 1

and timestamp (hence three dimensional mapping) into associated

3. It is not a relational database and can be better defined as a sparse,
distributed multi-dimensional sorted map.
4. BigTable is designed to scale into the petabyte range across "hundreds
or thousands of machines, and to make it easy to add more machines to
the system and automatically start taking advantage of those resources
without any reconfiguration".

12. The rise of Not only SQL - 2
Facebook's Way

13. The rise of Not only SQL - 2
1. It is a NoSQL solution that was initially developed by Facebook and
powers their Inbox Search feature.

14. The rise of Not only SQL - 2
1. It is a NoSQL solution that was initially developed by Facebook and
powers their Inbox Search feature.
2. Jeff Hammerbacher, who led the Facebook Data team at the time, has
described Cassandra as a BigTable data model running on an Amazon
Dynamo-like infrastructure.

2. Jeff Hammerbacher, who led the Facebook Data team at the time, has
described Cassandra as a BigTable data model running on an Amazon

3. Cassandra is an open source distributed database management
system.

3. Cassandra is an open source distributed database management
system.
4. It is an Apache Software Foundation top-level project designed to
handle very large amounts of data spread out across many commodity
servers while providing a highly available service with no single point of
failure.

17. The rise of Not only SQL - Others
Hadoop / HBase
Hypertable
Amazon SimpleDB
MongoDB
Terrastore
CouchDB
MemcacheDB
And Many others {{The list is Endless}}.
