This WordPress database has a definite default MySQL structure that allows your websites to function well. However, you can even add more tables to customize it in the way you want. In the WordPress database, the shelves are called tables.
The Database Host
The database of your WordPress is basically the computer hosting your database on a MySQL server. To take an example, a database host is an actual house that you can go to with a hostname, which means a database name. You can get all the information from the room section, which is the database name.
You require permission for that, and this is why you need to enter the username and password before entering the house. In most of the scenarios, you can use the local host to manage and connect your WordPress with your database.

What is Database Table?
Your data is stored in tables in the database. Each table has unique data and is displayed in rows. The rows also contain different pieces of information or parameters. WordPress will automatically create tables when you set up the website.

What is an SQL Query?
SQL is basically the Structured Query Language, a programming language used to manage the database. WordPress and database both communicate through SQL queries. In simple words, whenever, WordPress needs to display any type of information, it sends an SQL query. The MySQL server then processes it and gives back results with the right data. WordPress also makes use of the MySQL queries to store or retrieve any type of data and then generate it into web pages. The following is an example of a MySQL query:
SELECT * FROM wp_posts WHERE ID = 20;
You can perform several actions like insert, update, and delete. Say, for example, you want to delete an unwanted post, you can run the below query:
DELETE * FROM `wp_posts`<br> WHERE `post_type` = 'post'<br> AND DATEDIFF(NOW(), `post_date`) > 20
You can remove the spam and older posts from the WordPress interface manually, but with Query you can do it just quickly!
