Drupal termnology

Basically, there are 5 main layers in Drupal where information flows,

  1. Data (Node, ETC)
  2. Modules
  3. Blocks and Menus
  4. User Permissions
  5. Template


Base of the system is collection of Nodes. – the data pool

These are functional plugins that are either part of the Drupal core (they ship with Drupal) or they are contributed items that have been created by members of the Drupal community.

Blocks and Menus
This is the next layer where we find blocks and menus. Blocks often provide the output from a module or can be created to display whatever you want, and then can be placed in various spots in your template (theme) layout. Blocks can be configured to output in various ways, as well as only showing on certain defined pages, or only for certain defined users.

User Permissions
Here is the next layer where settings are configured to determine what different kinds of users are allow to work and see.

This is mainly the site theme or the skin. This is made up predominantly of XHTML and CSS, with some PHP variables intermixed

Understanding this flow of information is very important if you are facing A Drupal project targeted interview as the interviewer might test your overall knowledge  of  Drupal CMS by asking this sort of questions.







What is taxonomy in drupal?

We can define any number of vocabularies (category types) and terms (categories)
Controversial Content: (vocabulary)
– violence (term)
– adult content (term)

Genre (Vocabulary)
– Comedy (term)
– Romance (term)

We can config which content types are compatible with which vocabulary and which nodes are belong to which terms.

Some important drupal modules: Views, CCK, Path auto, FCK Editor, User points, Flags, Panels, Image cache


What is a block?

Block is a section in a page (recent posts, news, vote to something, login box, navigation), which is movable to regions (header, footer, content top etc) in a page. Blocks can be configured to show/hide only to certain type of user roles, url patterns or some other advanced criteria. (Content area is not a block)

What is a node in Drupal?

A node is a unit of content. It has a type. Page, News or as Testimonial.

Drupal Modules

These key modules are some of the most important ones to add no matter what type of site you want to build with Drupal.

We need  TOKEN module http://drupal.org/project/token

  • IMCE for uploading images to insert into posts
  • Poor Mans Cron for easy execution of the Drupal cron file

What is VIEW Module ?

VIEW is a powerful query builder for Drupal that allows you to fetch and present lists and tables of content (posts/nodes) to the user in ways that are tailored to your site and your content.

The Views module provides a flexible method for Drupal site designers to control how lists and tables of content (nodes in Views 1, almost anything in Views 2) are presented. Views can be used to generate reports, create summaries, and display collections of images and other content.


You need Views if:

  • You like the default front page view, but you find you want to sort it differently.
  • You like the default taxonomy/term view, but you find you want to sort it differently; for example, alphabetically.
  • You use /tracker, but you want to restrict it to posts of a certain type.
  • You like the idea of the ‘article’ module, but it doesn’t display articles the way you like.
  • You want a way to display a block with the 5 most recent posts of some particular type.
  • You want to provide ‘unread forum posts’.
  • You want a monthly archive similar to the typical Movable Type/Wordpress archives that displays a link to the in the form of “Month, YYYY (X)” where X is the number of posts that month, and displays them in a block. The links lead to a simple list of posts for that month.
