What does using a Content
Management System (CMS) buy you?





Content and settings stored in a database: edit
content, menus, navigation, etc. on the web
Web pages are generated by scripts from
information in the database, not stored as individual
files
Enter information once, display in different ways on
different pages (lists, grids, calendars, …)
Content is separate from style/presentation, so style
is consistent across site
Permissions system: different users have permission
to do different actions on the site
What are your options?



Many people testing it, finding security issues, etc.
Many modules freely available from developers
Many people donating their time to writing documentation, helping new

Flexible architecture



You don’t have to pay for a software license
You can modify the software
You can create your own modules for custom features
You can create your own themes for custom design
Based on standards:


Core software is PHP/MySQL, giving many hosting options
Output uses XHTML, CSS, JavaScript, so compatible with most browsers
Disadvantages of Drupal

Flexibility = Complexity




May not be the best alternative for simple or singlefunctionality sites
Takes some time to learn

Technology of Drupal

Drupal runs on a “LAMP” platform:
–
–
–
–
L = Linux operating system(but it can also
run on Windows, Mac)
A = Apache web server (but it can also run
on other web servers; not so well on
Microsoft IIS as on Apache)
M = MySQL database (but it can also run on
PostgreSQL, SQLite, and others)
P = PHP scripting language (no choices
there!)
Drupal Terminology

Module
 Def: Add-on code that adds functionality to Drupal
 Can be core (comes with Drupal), contributed (download and
install separately), or custom (written specifically for your site)
 Examples: Forum, Blog, Web Form

Theme
 Def: Set of PHP files, CSS files, and images that defines the
layout and styles for your site
 Can be core, contributed, or custom

Path
 Def: Part of the URL of your site that follows the base URL for
your site. For example, in http://example.com/node/add, the path
is “node/add”
Drupal Terminology p. 2


User
 Def: Anyone who visits your site
 Non-logged-in visitors are known as anonymous
 Users with accounts are assigned to roles that you can define,
such as Master Admin, Content Editor, Member
 Permissions are generally assigned by role
Content Item (called “Node” prior to Drupal 7)
 Def: A piece of content on your site, which could be displayed on
its own page or as part of another page (or both)
 Basic content items have a Title, Body, a unique ID number, and
some meta-data (creation time, last updated, author, etc.)
 Each item also has a content type, such as “Page”, “Article”,
“Press release”, “Event”, or “Member profile”.
 Content types can have additional custom fields besides Title and
Body, such as location, event date, banner image, etc.
Drupal Terminology p. 3

Taxonomy


Menu


Def: List of links to pages on your site, generally used for
navigation in headers, sidebars, footers
Weight


Def: Categories, tags, or other classifications that can be
applied to content on your site
Def: Number that defines the order of a list, such as of
menu items. Larger numbers “sink” to the bottom of the list.
Block

Def: Text, links, images, etc. that can be placed in a region
of your site’s theme (header, sidebar, footer, etc.), and
configured to display on one or more pages
