What are the supported databases by Drupal?

by

Drupal supports MySQL/MariaDB, PostgreSQL, and in Drupal 7 SQLite.

The correct answer to the question “What are the supported databases by Drupal?” would be:

Drupal primarily supports the following databases:

  1. MySQL/MariaDB: This is the most commonly used and recommended database for Drupal installations. It’s open-source, widely supported, and performs well with Drupal.
  2. PostgreSQL: Drupal also supports PostgreSQL, offering an alternative for users who prefer this database management system. It provides robust features and is known for its stability and reliability.
  3. SQLite: Drupal supports SQLite for development and small-scale deployments. It’s a lightweight, file-based database system that doesn’t require a separate server, making it convenient for testing and simple installations.

Overall, while Drupal primarily supports MySQL/MariaDB, it also offers compatibility with PostgreSQL and SQLite, providing flexibility for different use cases and preferences.
