Drupal is an open-source content management system (CMS) written in PHP that allows users to collaboratively create, edit, publish and manage various kinds of digital content. It provides a user interface for adding and editing content, and helps manage complexity by providing a means for collaboration. Drupal uses a modular architecture that separates functionality into modules and themes that can be managed through the user interface. Content in Drupal is organized into nodes that reside in content regions and can include other blocks like views, widgets and menus.

- 2. What is Drupal? Open Source software written in php. A CMS or content-management system. A sophisticated web application building tool.
- 3. What is a CMS? Simply put, a CMS is a website you build using the website itself. Wikipedia definition: A content management system ( CMS ) such as a document management system (DMS) is a computer application used to manage work flow needed to collaboratively create, edit, review, index, search, publish and archive various kinds of digital media and electronic text .

- 5. Why use a CMS? It helps manage complexity. It provides a user interface (UI) for adding, editing and publishing content. It provides a means for collaboration among many to perform the above tasks.
- 6. What is a UI? UI is a user-interface, which is a general term for the layout of options, widgets and settings used to configure the system or manage content. ‘ Site-building’ activities refer to configuring settings or managing content through the UI, such as building navigation menus.
- 7. Drupal Structure Drupal is a database-driven (‘dynamic’) application. It requires a database. Drupal has a core filesystem whose functionality can be extended using the UI itself, modules and themes. The UI settings are stored in the database.
- 8. Modules Packages of files in a directory that you upload into drupal’s module space (/sites/all/modules) Add functionality to drupal ‘ Core’ Modules come shipped with drupal ‘ Contributed’ Modules are downloads from drupal.org
- 9. Using Modules A newly enabled module will add an administration menu. Go to that module and read the help before changing anything. Play around and learn it’s feature set. Install the ‘Advanced Help’ module to get more verbose help with modules.
- 10. Themes Packages of files in a directory that you upload into drupal’s theme space (/sites/all/themes) Themes adjust the site layout and style. Like ‘skinning’ your media player. Themes can be easily changed in the UI.
- 11. Drupal Database Drupal’s database tracks things like : Site and Module settings, User’s information, Access information, Logging information, Permissions and User Roles, System Paths Content and content metadata
- 12. Nodes A node is the primary form of content in a drupal site. At a minimum it is a title and a body, and can be ‘specialized’. A ‘page’ and ‘story’ for example are node types that have a specific node settings. A node type is a blueprint for creating instances of content of a particular type.
- 13. Layout and Regions A Region is an area in a layout, such as a header, footer, content, left/right sidebar into which blocks can be placed and arranged. A block is a box containing some information A node resides only in the content area of the layout (except in special circumstances). Think of the content region as a big ‘node’ block that allows other blocks in it but the node itself can’t move.
- 14. Blocks Blocks are added by modules. Blocks can contain views, widgets, menus, nodes (in special circumstances), and panels. Blocks can be moved around through the UI Blocks can be styled individually.
- 15. Users All CMSes (wordpress, Joomla, Drupal) have a user login system; users have a username/pw. Drupal also supports the concepts of 1) Roles and 2) Permissions. Roles are user designations to groups having the same set of permissions.
- 16. Anonymous User A (not-logged-in) site visitor is called a ‘guest’, ‘visitor’ or ‘anonymous user’. Has a user-id (uid) of 0 (zero). All anonymous users belong to the ‘anonymous user role’ (a role ID of 1) and have a set of permissions assigned to them.
- 17. Authenticated User A user in drupal may belong to one or more roles. Every registered user in Drupal belongs to at least the ‘authenticated user’ role. Authenticated user role has a role ID of 2
- 18. Root ‘Admin’ User The ‘root’ user or ‘root admin’ has the ability to do anything on the site and is a special user. The ‘root’ user has a user-id (uid) of 1. The ‘root’ user does NOT have role-permissions to set because they are effectively gods within Drupal.
- 19. Managing Permissions KEY concept: if you grant permission to an authenticated user, it applies to ALL roles except the anonymous user. To grant a permission to everyone on a site, you must grant the permission to both the anonymous user and authenticated user.
- 20. Managing Permissions To grant permission to only a newly created ‘dentist role’, tick the permission on that role. Leave all the other roles deselected. If you grant to both the ‘dentist role’ AND the ‘authenticated user’ role, you would be doing it wrong. Drupal assumes you know this.
- 21. Downsides to the Druup Drupal has a steeper learning curve than wordpress or Joomla. Drupal and it’s developers make no excuse for this fact- it is a robust, flexible tool That said, the drupal community is constantly addressing usability and user-experience issues because they want the industry market share.
