everything you ever wanted to know about databases

What is Database?

The DataBase is a set of organized and structured data. In computer language, it is a software used to store and manage the data.

For Example, you have a cabinet having different sections in it. Each section has its files/data. And when you need some data to say images, you will choose that particular section (table) having images.

And you need to open/close, fix, secure that cabinet, so you’re managing, that cabinet right?. Just like that, WordPress uses MySQL as a Database Management system. Like, WordPress MySQL is open-source software.

MySQL works best with other software, like, LiteSpeed, Apache Web Server, PHP, and Linux operating system.

You need MySQL DataBase to install WordPress. That’s why all Hosting providers give MySQL all of their Hosting plans. And best Hosting providers offer 1-click installation for WordPress. You need to provide WordPress, with your MySQL information and it will handle the rest.

What is a DataBase Host?

A Host is a computer that is hosting your DataBase on a MySQL server. Hosting providers might be using a different name to manage MySQL servers. You can find them in your DataBase or MySQL section (in your Hosting Panel). You can reach out to your hosting provider for that concern.

What is the SQL Query?

SQL issue instructions to DataBase servers to manage data. Guidelines issued by SQL are called queries. WordPress uses these queries to retrieve data to manage it and create Web Pages.

SQL stands for Structured Query Language. It is a programming language.

A standard MySQL query looks like.

 1 SELECT * FROM wp_posts WHERE ID = 23;

SQL can update, insert, delete, or create new tables. That’s how WordPress manages all the data by using SQL strings.

What is Database Table?

Like, the cabinet has sections. The DataBase has tables, which it uses to store and manage the Data. Like an ordinary table, each table has columns and rows. And each row is used to store data in it.

For Example, a standard table could be.

Patient_Name

 Patient_Age

 Patient_Joinining date

 Patient_Phone no

 Patient_Address

Like so, WordPress will also create tables in your database.

For example, a default table created by WordPress could be.

wp_comments

 wp_postmeta

 wp_posts

 wp_links

 wp_terms

 wp_terms_relationships

 wp_terms_taxonomy

And these tables would have different columns.

For Example, for the wp_users, the columns could be.

Id

 user_login

 user_password

 user_name

 user_nickname

 user_url
