Introduction

Drupal is a robust, open-source Content Management System (CMS) and web application framework written in PHP. Known for its flexibility, scalability, and modularity, Drupal is widely used in information technology to build dynamic websites, enterprise portals, e-commerce platforms, and government applications.

Unlike lightweight CMS solutions, this is designed for developers and organizations that need advanced customization, security, and content workflows. It provides IT teams with the ability to create highly structured content, manage users with complex permissions, and extend functionality through thousands of community-contributed modules.

Since its release in 2001 by Dries Buytaert, it has grown into one of the leading enterprise-grade CMS platforms. It powers millions of websites worldwide, including government portals, higher education websites, healthcare platforms, NGOs, and global enterprises.
