You can then create tables to store your data and insert data into those tables.

For example, you can create a table called “products” with columns for product name, description, price, and availability.

You can then insert data into this table using SQL commands or a GUI tool.

You can also update and delete existing data in your tables using SQL commands or a GUI tool.

For example, you can update the price of a product or delete a product from the “products” table.

It is important to backup your database regularly to prevent data loss.

You can backup and restore data using SQL commands or a GUI tool.
