The start of data storage is from the creation of a database. As the name suggests database is a base for data. A database typically contains different tables based on the necessity of data storage.
SQL Create Database
In this section, we will see how different databases provides the feature of creating a database. So let’s start with the following set of databases.
We will try to understand database creation in each of the above mentioned DBs one by one.
PostgreSQL Create Database

The same database can also be created using SQL command. Please find below the command for the same.
CREATE DATABASE "TestDB" WITH OWNER = postgres ENCODING = 'UTF8';
MySQL Create Database
MySQL is the world’s most popular open source database. We will try to understand how to create a database in MySQL using SQL command.

CREATE DATABASE <database_name>
Example for creating a database

Also for Unix, database names are case-sensitive so please make sure that appropriate case is used.
We can use
show databases; to check if the database has been created successfully or not.
