@Med7atDawoud

The road to mongo*

* mongo from “humongous”

What is this

sessionAbout ?

OK, actually I will tell you

Two Important Facts

“Mesh Cloud” Means .. “Not about Cloud ”

1st

I’m interested today in “NoSQL” Concept.

2nd

so..?What is the relationship between

NoSQL and Cloud

Both are focus on solving the same

issue ..!

Scalability*What does it mean ??

* Scaling is the ability to enlarge your DB

is the facility of scaling the system according to

requirements

Scalability

Types of scalability

Vertical scalability (scale up) :* to add resources to a single node in a system* single point of failure* easy to be done, because it’s the same implementation only you scale hardware

Horizontal scalability (scale out) :

* means to add more nodes to a system

* No single point of failure*complex in implementation

Ok, lets get started

So, What makes me leaveMySQL for example and use

NoSQL?

NoSQL features that will suitable for

your needs

such as ..

There is no joins

No Complex Transactions

Horizontal Scalablearchitecture

New Data Modes

Data Models

Key/valuememcached , Dynamo

TabularBigTable (Google)

Document OrientedmongoDB, couchDB, JSON store

* from http://www.mongoDB.org

If we speak specially about

We’ll find new special features

It saves data in a JSON-style Documents

Represented as BSON

{“Hello” : ”world”}

\x16\x00\x00\x00\x02hello\x00\x06\x00\x00\x00world\x00\x00

Flexible Schemas

{"author":"Medhat“, "text":"..."}

{"author":"Medhat","text":"...","tags":["mongoDB"]}

Dynamic Queries

Focus on performance

Replication

Slave-Master Replica sets

Auto-sharding

And more other features* …

Go online to get them allhttp://www.mongodb.org

* I’ll try to explain each of them in isolated sessions

Support many programming languages*

JavaJavaScript

Perl

PythonRuby

C
