What is Database

1. What is Database hostguid.com/what-is-database A database is a collection of data that is structured and organized. A database is a bit of software that stores and organizes data in the computer world. Imagine is a file cabinet where data is organized into sections called tables. When you want a certain file, you go to that area (table) and get the file (data) you need. WordPress’ database management system is MySQL. Mysql is a relational database system that allows you to create, save, and retrieve data when you need it. MySQL, like WordPress, is an open-source program that works well with other open-source software such as the Apache web server, PHP, and the Linux operating system. A MySQL database is required to install WordPress. MySQL is included in the hosting packages of all WordPress hosting providers. You provide WordPress your database information during the installation and WordPress takes care of the rest. What is Database Host The computer that hosts your database on a MySQL server is known as the database host. Localhost is most of the time, and typing localhost in the host field will connect WordPress to your database. Some web-hosting providers, on the other hand, may manage MySQL servers under different hostnames. Your hostname may be found in your hosting control panel’s MySQL or Database sections. If you can’t find the hostname, contact your hosting provider. What is Database Table 1/4

2. Tables in databases are similar to sections or cabinets in a database system. Each table includes columns, and data is organized into rows. Each column in the table has its own field in each row. Example: an office database may have a table called employee_records . This table may have following columns: 1. employee_id 2. employee_name 3. employee_joining_date 4. employee_phone_no WordPress will automatically create tables inside your database. At the time of writing this, a default installation of WordPress would create the following tables: 1. wp_commentmeta 2. wp_comments 3. wp_links 4. wp_options 5. wp_postmeta 6. wp_posts 7. wp_terms 8. wp_term_relationships 9. wp_term_taxonomy 10. wp_usermeta 11. wp_users Each of these tables would have different columns where data is stored. For example, wp_users the table in WordPress has these columns: 1. ID 2. user_login 3. user_pass 4. user_nicename 5. user_email 6. user_url 7. user_registered 8. user_activation_key 9. user_status 10. display_name 2/4

3. What is SQL Query SQL is for Structured Query Language, and it is a programming language for managing databases. A query is a SQL command that instructs the database server to retrieve data. WordPress retrieves data from MySQL queries and uses it to generate web pages. A typical MySQL query looks like this: SELECT * FROM wp_posts WHERE ID = 23; SQL isn’t just for finding data from tables. It can also create new tables and update, insert, and delete data from existing tables. By saving and retrieving data from the database using SQL queries, WordPress stores, and editing all of your website data.
