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 Content Management Systems (CMS)
are available:


Drupal


Joomla


WordPress


Expression Engine


WebGUI


Plone





Advantages of Drupal


Free and Open Source

software


You don’t have to pay for a software license


You can modify the software


Large and vibrant
community

of users and developers


Many people testing it, finding security issues, etc.


Many modules freely available from developers


Many people donating their time to writing documentation, helping new
users, etc.


Flexible architecture


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 single
-
functionality sites


Takes some time to learn


Takes some time to set up


Free and Open Source = No guarantees


Free support options may or may not be responsive (but
you can pay for support)


Features you need may or may not be available


Your feature requests and bug reports may or may not be
acted upon


What types of sites is

Drupal good for?

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

applied to content on your site


Menu


Def: List of links to pages on your site, generally used for
navigation in headers, sidebars, footers

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
