unlimited number of rows and every data present inside the database
is properly structured with Predefined Schemas, it is basically used
to manipulate Relational Databases Management Systems.
A NoSQL Database is a Distributed Database where the data is very
unstructured with Dynamic Schema. Unlike SQL it cannot have unlimited
rows but it follows a Standard Schema Definition and can store all
sorts of data models with large distributed data in the form of
key-value pairs, graph databases, documents or wide-column stores./* KEY DIFFERENCE
SQL 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.
SQL databases are table based databases whereas NoSQL databases can be document based, key-value pairs, graph databases.
SQL databases are vertically scalable while NoSQL databases are horizontally scalable.
SQL databases have a predefined schema whereas NoSQL databases use dynamic schema for unstructured data.
SQL requires specialized DB hardware for better performance while NoSQL uses commodity hardware.*/
