The educational Web site challenge


Campus Web sites
-

on of the biggest challenges that
institutions of higher education have been faced with.



They have typically grown from ad hoc sites to essential
sources of marketing and academic information and
communication.



They have become inevitable part of educational
process containing all necessary information, white
papers, tutorials, and news regarding exams.





The educational Web site challenge


The clear conflict between the expectations of
the users and the capacity of webmasters.



The problem is especially critical because of the
highly decentralized environment with very
limited budget.



The solution: adopting the new technologies


CMS (Content Management System)


The content management system (CMS) can be defined
as a tool for manage, store, retrieve and publish
content.




If the primary goal for the content is to be published on
the Web, than the CMS is referred to as the Web CMS



Typically, a CMS consists of two elements: the content
management application (CMA) and the content
delivery application (CDA).

Benefits from using CMS

enabling people who are not familiar with it to
administrate content on the site.

pages every day to enter the new information. A CMS
can distribute this work to individuals.

Privileges


rights for module access


The privileges are defined for specific user or group of
users on specific module through their accounts.


Every single privilege has its own value that is power of
two.


So far we identified privileges of read, write, delete,
publish and administrate and assign them values of
1,2,4,8 and 16 respectively.


Set of privileges for concrete user on concrete module
is sum of values of single privileges.

User management


manipulation with users and their accounts


allows association users in groups


administrators can determine groups; managing user
memberships in particular groups, and gives
administrative privilege for specific user on specific
group


group administrators can assign other users to specific
group and also can define other group administrators


all administrators of specific group have equal rights

User management (2)


provides creating new users and groups



updating existing accounts



setting and unsetting system administrator’s

privilege for specific user



defining user membership in groups

Content converter


is connection between front end and back office


defines mapping that convert module structure
to menu tree according defined limitations


allows that user from internet can view only
content that is located in modules with selected
flag “public”


users with defined user account can view
content according their user profiles

Classes of users

Conclusion


One of the biggest challenges that institutions of higher
education have been faced with is the one of their Web
site


This problem is further complicated because there are
increased expectations

from future or current students
and faculty staff,

about what the web site should
provide.


Using an CMS can help to reduce costs, and improve
efficiency of Web site maintenance.


In this paper, some of the main benefits from using a
Web CMS are presented.
