1A SQL Database follows a table like structure which can have an 
2unlimited number of rows and every data present inside the database 
3is properly structured with Predefined Schemas, it is basically used 
4to manipulate Relational Databases Management Systems.
5
6A NoSQL Database is a Distributed Database where the data is very 
7unstructured with Dynamic Schema. Unlike SQL it cannot have unlimited 
8rows but it follows a Standard Schema Definition and can store all 
9sorts of data models with large distributed data in the form of 
10key-value pairs, graph databases, documents or wide-column stores.

1/* KEY DIFFERENCE
2SQL pronounced as "S-Q-L" or as "See-Quel" is primarily called RDBMS or Relational Databases whereas NoSQL is a Non-relational or Distributed Database.
3SQL databases are table based databases whereas NoSQL databases can be document based, key-value pairs, graph databases.
4SQL databases are vertically scalable while NoSQL databases are horizontally scalable.
5SQL databases have a predefined schema whereas NoSQL databases use dynamic schema for unstructured data.
6SQL requires specialized DB hardware for better performance while NoSQL uses commodity hardware.*/
