Management Framework, its capabilities
extend from content management to enabling a
wide range of services and transactions.

programming interface, basic web site

accomplished with no programming

Drupal runs in many environments, including
Windows, Mac OS X, Linux, Free BSD, Open
BSD, Solaris 10, Open Solaris and any platform
that supports either the Apache (version 1.3+), or
IIS (version IIS5+) Web server and the PHP
language (version 4.3.5+). Drupal requires a
database such as MySQL or PostgreSQL to
store content and settings

where did it come from?
originally written by Dries Buytaert as a bulletin board
system, Drupal became an open source project in
2001
Drupal is an English rendering of the Dutch word
“druppel,” which means “drop,” as in droplet
from May 2007 to April 2008, Drupal was downloaded
from the Drupal.org website more than 1.4 million
times, an increase of approximately 125% from the
previous year
as of August 2008, Drupal 6.4 is the latest release.
Drupal is a winner of several Packt Open Source
CMS Awards

Drupal Core- the official release, known as
\"Drupal core\", contains basic features
common to most CMSs. these include the
ability to register and maintain individual user
accounts, administration menus, RSS-feeds,
customizable layout, flexible account
privileges, logging, a blogging system, an
Internet forum, and options to create a
classic“brochureware“ (static, rarely updated)
Web site or an interactive community Web
site

taxonomy system which allows content to be
categorized or tagged with keywords for
easier access

feature updates by version

The Drupal core includes several \"core themes\",
which customize the aesthetic look-and-feel of the
site. these themes can be chosen by the
administrator via a special menu
The Color Module, which was introduced in Drupal
core 5.0, allows administrators to change the color
scheme of certain themes via a Web-browser

extending Drupal core-
designed to be modular with a system of \"hooks\"
and \"callbacks\", which are accessed internally
via an API. this design allows third-party
\"contributed\" (often abbreviated to \"contrib\")
modules and themes to extend or override
Drupal's default behaviors without changing
its’ core's code

extending Drupal core (continued)-
Drupal's modular design, which isolates its
core's files from contributed module and
themes, increases flexibility and security and
allows Drupal administrators to cleanly
upgrade to new releases of Drupal core
without potentially overwriting their site's
customizations

what does it all mean?
to some, using Drupal is a challenge
lack of object orientation-Drupal exclusively uses procedural
programming, not object-oriented programming (OOP). results are
less efficient code reuse since object inheritance is \"weak\" and
polymorphism is only approximated in the rendering layer
poor usability- aspects of Drupal's administration interface can be
confusing and intimidating, particularly for new administrators. some
say Drupal lacks an intuitive, easy administration user interface
steep learning curve-Drupal may be powerful, but it is also complex.
The key is overcoming its steep initial learning curve. most casual
users are willing to sacrifice features for ease of use making Drupal
less popular than more user-friendly CMS's despite its enhanced
functionality
