What is the difference Between SQL and NoSQL databases?

Question

I don't have enough knowledge about databases but thinking to start working with them. But got confused between SQL and NoSQL databases. And also tell me which is good SQLite or MySQL.?

Answer 1

SQL databases are relational, NoSQL are non-relational

Means that

In SQL data base data are stored in tabular format.

While in No SQL database values are stored in key and pair structure.
