If I say easily Mongo DB is a Document Oriendted Database, but MySQL is RDBMS or Relational Database Management System.
In MySQL data store in some columns and rows. But in Mongo DB store data like as JSON-like documents.
In MySQL data store in some columns and rows. But in Mongo DB store data like as JSON-like documents.
We can imagine a MySQL table like as
First_Name -------- Last_Name -------- Salary
Bill -------------------- Gates --------------- 200
Larry ----------------- Page ---------------- 350
Amir ------------------ Khan --------------- 150
Bill -------------------- Gates --------------- 200
Larry ----------------- Page ---------------- 350
Amir ------------------ Khan --------------- 150
Now if we see the table in Mongo DB, then it will look like as
{
{
'_id' : Objectid (
'First_Name' :
'Last_Name' :
'Salary' :
},
'First_Name'
'Last_Name'
'Salary'
},
{
'_id' : Objectid (
'First_Name' :
'Last_Name' :
'Salary' :
},
'_id'
'First_Name'
'Last_Name'
'Salary'
},
{
'_id' : Objectid (
'First_Name' :
'Last_Name' :
'Salary' :
}
'_id'
'First_Name'
'Last_Name'
'Salary'
}
.
Now what is the opportunity of Mongo DB, why I'll leave MySQL:
=======================================================
=======================================================
>> It's so fast than RDBMS like as MySQL
>> It has a great feature Horizontal Scalability, which have no in MySQL
>> MySQL is not able to store Large Scale Data, but Mongo DB isfor
>> If you're a developer and if you need to develop a modern applic ation with Big Data, then MySQL isn't good for you, you need to choice MongoDB.
>> If you use MySQL in server and if you get million million requests, then your server will crash. Because, MySQL can't process huge request.
>> Mongo DB can work in multiple server.
>> In one word we can say that Mongo DB can work with massive data. It's created for it.

You can think about Google Map. There has a lot of data in Google Map and they process billion billion data in every minute.
>> There has features field, range queries ও REGEX in Mongo DB.

>> Mongo DB
>> Mongo DB supports most of the OS like as: Windows, Linux, Mac OSX, Sun Solaris etc.

Now I'll start to use Mongo DB by leaving MySQL?
=============================================
=============================================
Nope. Why not? Before you need to some drawback in Mongo DB.
>> JOIN operation is a great feature in MySQL. By using it, we can query in multiple table. In Mongo DB has no JOIN operation.
>> Complex Transaction is another great feature of MySQL/RDBMS. It's absent in Mongo DB. Like as: if you develop travel & a tourism booking application, then you need Complex Transaction & Join. For this reason MySQL if flexible than Mongo DB.
Now who is the best? Answer- nobody. You'll choice as your needed. If you need Complex Transaction & Join, then you'll choice MySQL. If you need to process big data, you'll choice Mongo DB.
It's something like as chopper and knife. You'll use the chopper for shearing coconut and you'll use the knife for the butter.
Some best tutorial for learning Mongo DB:

Which company are using Mongo DB:
=================================
=================================
Facebook → Facebook adapted the storage engine API, extending MongoDB into new workloads and new capabilities.
The New York Times → A great newspaper in the world.
EA → Great game developer company.
CISCO → A world leader in Networking
These companies also use Mongo DB- MTV Networks, Adobe, Craiglist, Forbes, The Washington Post, Stripe, Hudl, Metlife
Last of all MongoDB is Scalable, Agile and Cloud Ready. It is awesome. If you want to be ready for the future, then learn Mongo DB.
