5. Presentation Administration
Handle the appearance of a Joomla web site
Template Manager
Language Manager
Learned already in the previous chapter
: Information Retrieval

6. Language Manager Allow prev. installed languages to be configured
Default language for a site is the language displayed to new users
However, each individual registered user is allowed to select a preferred language for presentation
Separate set, thus allowing the web site to present in a language, but admin in the other one
: Information Retrieval
Administering Joomla!

7. Language Manager (cont.)
In essence, language settings are quite flexible for:
particular users
the web site
the Administrator interface
Recall that individual articles can also be configured to use a different language

10. Content Administration
Handle works related to various form of contents (article, media), sections, categories, involving:
Section Manager and Category Manager

Although the Media Manager handles all types of media (including sound and video), most Joomla admin use it primarily to administer images
Various types of files format (e.g. with extensions: gif, png, ppt, swf, pdf, xls, …) can be supported

17. System Administration
Handle works related to the site, system and server, including:
Global Configuration Manager: global settings
User Manager: admin the user accounts
Menu Manager: create & edit of menus, or the menu items used by each menu
Extension Manager: add & remove of new extensions/languages
Module Manager, Plugin Manager & Template Manager: provide management functionality for each of specific add-on types
Mass Mail Manager: create a bulk mail transmission to either selected user groups or all users of the system

18. Control Panel Act as a home page for the admin task
Also, serve as a good launching point for examining the system options

27. Login Security
Joomla provides anonymous access for everyone and basic login security for registered users.
Three types of users are classified:
Unregistered users
Visitors who haven’t logged in
Registered front-end users
Readers who log in to gain access to restrict content
Registered back-end users
Users who are granted permissions for making changes to the site
: Information Retrieval
Administering Joomla!

28. Login Security: Registered Front-End Users
Contains 4 groups of privileged users:
Registered:
Can read restricted content (if available), but can not submit new content articles
Author:
Can post and modify their own articles, even determine when the article will be published (under administrator’s setting)
Editor:
Like an author, + edit other contributors’ content
Publisher:
Like an Publisher + publish or unpublish content on the site
: Information Retrieval
Administering Joomla!

29. Login Security: Registered Back-End Users
contain 4 groups of administrative users of the site.
Manager:
Lowest authority, limited access to the admin Control Panel
can confirm registration for users
perform basic maintenance, e.g. categorizing an article or managing sections and categories
Administrator:
install and uninstall extensions to the system,
change the selected template & the layout of a page
modify the permissions of any user lower than their access level
: Information Retrieval
Administering Joomla!

30. Login Security: Registered Back-End Users (cont.)
Super-administrator (SA):
SA is the one who created during the initial Joomla installation, under the account name “admin”
Act as the king of the web site, therefore having no restrictions on the system
Similar to “root” of Linux
Depending on the user’s group designation, the administrator interface will appear differently
Ex: The interfaces for the lower-level groups (e.g. manager) are missing many of the buttons and menu items that are present when an SA is logged into the system

31. Menu Manager
Menu is a channel (or access point) to connect to every piece of content that is accessible through the Joomla system
We have used them already in the previous chapter when making links to the newly created contents

32. Menu Manager (cont.)
Q: How could we know what sort of users can access (or see) this particular menu?
: Information Retrieval

By clicking at the module name in the list will jump to the configuration screen of it

Ex: The banner module requires some priory info., e.g. Banner Client, that must prepare separately

a small back-end mail system so that users can send messages to the administrator users
: Information Retrieval
Administering Joomla!

39. Plugin Manager
Plugin: Add-on applications that sit between the Joomla system and the user interface, in order to change the way the Joomla normally performs
The most comprehensible plug-ins are perhaps the text editors used for modifying content.
The TinyMCE editor is actually a plug-in named tinymce
: Information Retrieval
Administering Joomla!

40. Mass Mail Manager
a small back-end mail system so that admin can send a bulk all of the site users for a site-related occasion, a maintenance shutdown, a security alert, or another event
Click here for options e.g. a subject prefix or body suffix (such as a site signature)
: Information Retrieval

41. Global Check-in Manager
It a mechanism for preventing conflicts of two users trying to make changes to the same document
When an article is being edited, it is automatically checked out to the user, and no other user can edit it until it’s checked in
However, web connection may be lost, or user may forget to checking in the displayed article
So, this feature will automatically checks in all items that are currently checked out

44. Backing Up the Joomla! Site
All of the content and many of the Joomla settings are held in the various tables in the Joomla database, which is the MySQL database
So, we need to use MySQL to back up our data store
: Information Retrieval
Administering Joomla!

45. Backing Up Through phpMyAdmin
phpMyAdmin is an open source utility program providing database export capabilities
The utility can export the complete database along with all contained tables and data
