It encompasses the logic, database interactions, and server configuration necessary for a fully functional website. The backend is built with server-side programming languages, including:

PHP
Python
Node.js (JavaScript runtime)
Ruby

Backend developers also work with various databases to store, retrieve, and manipulate data. Common database management systems include:

MySQL
PostgreSQL
MongoDB

The interaction between the frontend and backend is facilitated by APIs (Application Programming Interfaces), which allow different software components to communicate with each other.

Databases and Their Role in Web Development

Databases are integral to the functionality of any web application or site. They store all the necessary data, from user profiles to transaction records, and enable quick data retrieval and manipulation. Understanding how to design, maintain, and interact with databases is a crucial skill for any web developer. Key practices include:

Database normalization: Structuring a database in a way that reduces redundancy and improves integrity.
Indexing: Creating indexes on database tables to speed up query performance.
