A Content Management System (CMS) is a back end application which allows the front end of an application or website to be managed. It can have many features and functions depending upon the requirements of the system administrators. A CMS is being commonly used in most websites these days and there are many ready made CMS like Joomla, WordPress and Drupal which are readily available to be used.

Features of CMS can include:

a) Edit existing pages: A simple Content Management System can have a function to easily edit the text, navigation menu names, banners, galleries, images, PDfs, videos and all other media. This type of Content Management System is good for websites which would always have fixed pages.

b) Manage page counts: For sites which would need new pages to be added as well, a Content Management System with the function to add or remove pages is needed. When a new page is added, the navigation menu and the site map should automatically get updated. Similarly when a page is deleted from the system, the link to that page should be automatically erased from the navigation and the sitemap. The design of such sites have to be flexible enough to accommodate increasing or decreasing menus.

c) Manage forms: The administrators can add/delete forms or edit the existing forms.

d) Users types: Websites and applications which have many interfaces and functions cannot be managed by one single Administrator. An Admin user management function is added to allow multiple administrators to manage the website or application. The system has one main administrator who creates sub admin users. These sub admin users can be given access to only certain areas or to the full system. They can be deleted from the system and their details (like password, e-mail id, access areas etc.,) can be easily edited.

e) Manage design: A CMS can have a function to update the design template of the front end. This again can be as simple as changing the color scheme and the background of the template or as advanced as changing the complete structure of the design.

f) Manage Search Engine Optimization: If the CMS is for a commercial website then it should have a system to update the Search Engine Optimization elements on the website such as Meta tags, URLs, image names, ah-refs etc.,

A Content Management System can be either created from scratch using custom coding or from ready to use platforms such as wordpress, joomla and Drupal.
