Joomla is an award-winning content management system (CMS), which enables you to build Web sites and powerful online applications. This presentation will cover all of the highlights and features Joomla has to offer.
What is Joomla?
Joomla is an award-winning content management system (CMS), which enables you
to build Web sites and powerful online applications. Many aspects, including its ease-of-use and
extensibility, have made Joomla the most popular Web site software available. Best of all, Joomla is an
open source solution that is freely available to everyone.
In 2001 an Australian company developed a cms named mambo, two versions of the cms where published ,
the commercial(MCSM) version and the open source version MOS)., the open source version experienced
a great success .
Joomla History ?
In order to secure the existence and the continued development of Mambo, there were deliberations on all sides
in the course of the year 2005 to establish a foundation for the open-source version of Mambo.
On August 10, 2005 it finally happened: The Mambo Foundation was announced on the Mambo project
page. After the positive reactions in the first few hours, it quickly became obvious that Miro in Australia
established the foundation and that the developer team had not been included into the incorporation
modalities. Heated discussions erupted in the forums of the community and the developer team wrapped
itself in silence for a few long days.
So Miro no longer had a development team, and the development team decided to develop a new cms
called joomla which is based on Mambo.

Joomla is so much more than just a powerful content management system. Here is a list of features "out
of the box," but the true power of Joomla is in its extensibility.
Joomla has a registration system that allows users to configure personal options. There are nine user
groups with various types of permissions on what users are allowed to access, edit, publish and
Authentication is an important part of user management and Joomla support multiple protocols,
including LDAP, OpenID, and even Gmail. This allows users to use their existing account information to
streamline the registration process.
The Media Manager is the tool for easily managing media files or folders and you can configure the
MIME type settings to handle any type of file. The Media Manager is integrated into the Article Editor
tool so you can grab images and other files at any time.
There is international support for many world languages and UTF-8 encoding. If you need your Web site
in one language and the administrator panel in another, multiple languages are possible.
It's easy to set up banners on your Web site using the Banner Manager, starting with creating a client
profile. Once you add campaigns and as many banners as you need, you can set impression numbers,
special URLs, and more.
The Contact Manager helps your users to find the right person and their contact information. It also
supports multiple contact forms going to specific individuals as well as groups.
If you want to find out more about your users, it's easy to create polls with multiple options.
Help navigate users to most popular search items and provide the admin with search statistics.
Web Link Management
Providing link resources for site users is simple and you can sort them into categories, even count every
Joomla's simplified three-tiered system of articles makes organizing your content a snap. You can
organize your content any way you want and not necessarily how it will be on your Web site. Your users
can rate articles, e-mail them to a friend, or automatically save a PDF (with UTF-8 support for all
languages). Administrators can archive content for safekeeping, hiding it from site visitors.
On public Web sites, built-in e-mail cloaking protects email addresses from spambots.
Creating content is simple with the WYSIWYG editor, giving even novice users the ability to combine text,
images in an attractive way. Once you've created your articles, there are a number of pre-installed
modules to show the most popular articles, latest new items, newsflashes, related articles, and more.
Syndication and Newsfeed Management
With Joomla, it's easy to syndicate your site content, allowing your users to subscribe to new content in
their favorite RSS reader. It's equally easy to integrate RSS feeds from other sources and aggregate them
all on your site
The Menu Manager allows you to create as many menus and menu items as you need. You can structure
your menu hierarchy (and nested menu items) completely independent of your content structure. Put one
menu in multiple places and in any style you want; use rollovers, dropdown, flyouts and just about any
other navigation system you can think of. Also automatic breadcrumbs are generated to help navigate
your site users.
Templates in Joomla are a powerful way to make your site look exactly the way you want and either use a
single template for the entire site or a separate template for each site section. The level of visual control
goes a step further with powerful template overrides, allowing you to customize each part of your pages.
Integrated Help System
Joomla has a built-in help section to assist users with finding what they need. A glossary explains the
terms in plain English, a version checker makes sure you're using the latest version, a system information
tool helps you troubleshoot, and, if all else fails, links to a
wealth of online resources for additional help and support.
With Web services, you can use Remote Procedure Calls (via HTTP and XML). You can also integrate XML-
RPC services with the Blogger and Joomla APIs.
These are just some of the basic Joomla features and the real power is in the way you customize Joomla.

Extension Types and Their Uses
A Joomla! extension is anything that extends Joomla!'s functionality beyond the core.
There are three main types of extension: components, modules, and plugins.
There are also languages and templates, but these are solely designed to modify page
output, irrespective of the data being displayed
Joomla Extension Directory
Modules typically make up the elements of a sidebar or content menus. Modules complement the content
contained in a component; they are not intended to be the main substance of a page.
Modules are installed through the control panel , they dont manipulate any data form the database all what
they do is display content like in this example this module displays the weather.
More commercial and non commercial modules can be found here
More commercial and non commercial plug-ins can be found here
When a piece of code is needed throughout the site, it is best implemented as a plug-in
(formerly called a Mambot). Plug-ins are commonly used to format the output of a
component or module when a page is built. Some examples of plug-ins include keyword
also be used to extend the results found in the core search component. The back-end
controls are similar to those of modules.
ReadMoreExt can automatically add articles introduction's images
hyper links, and the hyper links will link to the complete article, just
like the ReadMore link. It applies to front page, section and category
This plugin forces user's registration to be approved first by an
administrator. The user email is first verified, then the administrator
will approve the registration. The template must include a position for
Multilingual registration approval

Components frequently have sophisticated back-end controls. The back end is commonly used to create and update
records in database tables, as an simple example a small guest book or a simple banner manager , where the user
has controls from which he can use the functionality .
Note:- A component can contains a module and a plug-in .
Joomla! has multilingual support, which enables us to present Joomla! in many different
languages. Language extensions include files that define translated strings for different parts
We use templates to modify the general appearance of Joomla!. There are two types of
template extension: site templates and admin templates.
Tools, although referred to as extensions, are very different to components, modules,
and plugins. The term 'tools' is used to describe any other type extension that can be
used in conjunction with Joomla!.
Joomla! 1.5 is a three tiered system
•The top, Extensions layer, consists of Extensions to the Joomla Framework and its
Modules , Components , Templates
•The middle, Application layer, consists of applications that extend the Framework JApplication class.
Currently there are four applications included in the Joomla distribution:-
•JInstallation is responsible for installing Joomla on a web server and is deleted after the v
installation procedure has been completed.
•JAdministrator is responsible for the back-end Administrator.
•JSite is responsible for the front-end of the website.
•XML-RPC supports remote administration of the Joomla website.
•The bottom, Framework layer, consists of:-
•the Joomla Framework itself.
•Libraries that are required by the Framework or are installed for use by third-party
•Plugins extend the functionality available in the Framework.
