  • Modules
  • Blocks and menus
  • User permissions
  • Themes and templates

In Drupal, the five conceptual layers in the system architecture are:

  1. Presentation Layer: This layer deals with how content is displayed to users. It includes themes, templates, and CSS stylesheets that control the layout and design of the website.
  2. Application Layer: This layer contains the logic for processing user requests and generating responses. It includes modules, hooks, and APIs that handle functionality such as user authentication, content management, and site configuration.
  3. Data Layer: This layer manages the storage and retrieval of data. It includes the Drupal database schema, entities, fields, and the Drupal database abstraction layer (DBAL) that provides a unified interface for interacting with different database systems.
  4. Configuration Layer: This layer stores configuration settings that define how the site behaves. It includes settings managed through the Drupal administration interface, as well as configuration files stored in the filesystem.
  5. Infrastructure Layer: This layer consists of the underlying infrastructure that supports the Drupal application. It includes the web server, database server, caching systems, and other software components required to run a Drupal site.

These layers work together to provide the functionality and flexibility that make Drupal a powerful content management system.
