What is Database and what is mysql?

Database is a systematic collection of data.Databases support storage and  manipulation of data. Databases make data management easy. Let's discuss few examples.

In simple words data can be facts related to any object in consideration.

For example your name, age, height, weight, etc are some data related to you.

A picture , image , file , pdf etc can also be considered data.

TYPES OF DATABASE :

There are 4 types of database namely 

1.Hierarchical

2.Network DBMS

3.Relational DBMS

4.Object Oriented Relation DBMS

WHAT IS SQL?

NoSQL is an upcoming category of Database Management Systems. Its main characteristic is its non-adherence to Relational Database Concepts. NOSQL means "Not only SQL". 

Concept of NoSQL databases grew with internet giants such as Google, Facebook, Amazon etc who deal with gigantic volumes of data.

When you use relational database for massive volumes of data , the system starts getting slow in terms of response time.

To overcome this , we could of course "scale up" our systems by upgrading our existing hardware.

The alternative to the above problem would be to distribute our database load on multiple hosts as the load increases.

This is known as "scaling out".

 NOSQL database are non-relational databases that scale out better than relational databases and are designed with web applications in mind.

They do not use SQL to query the data and do not follow strict schemas like relational models.With NoSQL, ACID (Atomicity, Consistency, Isolation, Durability) features are not guaranteed always
