Drupal

Drupal is an open-source content management system (CMS) written in PHP and developed by a global community since the early 2000s. It stands out for its flexible content modelling and granular permission system, which makes it suitable for advanced sites — from corporate portals to government and education platforms.

How Drupal works

Drupal is built on a modular architecture: the core provides the fundamentals, and almost any capability is added through modules. Key concepts include:

• content types — user-defined data structures with arbitrary fields;
• taxonomies — flexible systems for categorisation and tagging;
• Views — a tool for building content lists and reports without writing queries;
• roles and permissions — precise control over access to features and data.

The system uses a MySQL or MariaDB database and ships with caching mechanisms that improve performance.

Practical applications

Drupal is chosen where unusual content structures, multilingual support, strong security and scalability matter — hence its popularity in public administration, universities, media and large organisations. Compared with WordPress or Joomla it has a steeper learning curve but offers greater control over site logic, and it handles complex data models and fine-grained permissions across many editorial groups particularly well. It is also worth noting that the Drupal community places heavy emphasis on security — a dedicated team publishes regular fixes, which makes the system a trustworthy choice for sites processing sensitive data. To run a complex Drupal site reliably, it is worth pairing it with hosting that offers current PHP and enough database performance, because intricate queries and many modules raise server load, and that directly affects page load times as well as how comfortably editors work in the admin panel.
