What is CMS

A Content Management System (CMS) allows websites of any budget to quickly and efficiently build, deploy and maintain Internet, Intranet and Extranet websites.Why Content Management?
Web content management systems reduce costs and helps overcome potential barriers to Web communication by minimizing the cost of creating and contributing content, while ensuring accuracy. Content management systems also reduce site maintenance costs while ensuring usability and corporate branding.
Allow Efficient Use of Human Resources
Content management systems maximize the effectiveness of team skills by enabling business users to publish their own content. That's right, you no longer have to bother highly skilled technical staff to put up web page content. Besides, business users tend to be content experts, who know what content is likely to be relevant and useful to customers, unlike non-business workers (technical geeks).
Save Time & Money
Since anyone with a rudimentary knowledge of HTML can use the system, imagine the technical fees you can save by not having to call on your webmaster to correct a document, or create a new document which you've probably already written. Also, being at the mercy of an unavailable webmaster is no longer an issue since you can put up most content yourself.
