Generally, a Content Management System (CMS) is a system that manages the workflow, usually in a collaborative environment. This system is a collection of procedures that simplify some complex or repetitive tasks. These procedures can be manual or computer. Website management is one of the tasks that some system needs to create, edit and manage content. Web pages are a typical example of content. You need an editor to create pages, a database to store them, and a system to generate and retrieve pages when needed.
Web Content Management System (CMS) is a web application designed to create and manage HTML content: web pages. Web CMS is used to manage a large collection of web resources (text, HTML code, images, PHP scripts, etc.). Web CMS features generally include: content creation, content control, content editing, maintenance features, and special features for each CMS. In general, web content management software programs include authoring tools designed to allow users with little or no knowledge of programming or markup languages to create and manage content with relative ease. Therefore, you do not need to know anything about HTML, CSS, PHP, JavaScript, AJAX or other sophisticated codes.
Web visitor management kiosk use a database to store additional content, metadata, or data that the system may need. A web CMS generally contains a presentation layer that displays the content to site visitors based on a set of templates. A template is a basic page layout that contains content holders, page styles, and other unchanged page data.
Most CMS web applications use server-side caching to increase performance. This works best when web content doesn't change frequently, but visits regularly. Web CMS management is usually done through web-based interfaces, but some systems require the use of a desktop client. A Web CMS generally requires an experienced administrator to configure and add features, but it is primarily a site maintenance tool for non-technical administrators. It allows non-technical users to easily make changes to a site with little or no training.
There are many open source web content management systems that you can download and use for free. Some well-known free CMS systems are Wordpress, Joomla and Drupal, just to name the most popular. These are based on the PHP writing language. There are also other CMS applications based on other languages such as .NET, ASP.NET, Java, Java Bundle, Perl, Python, Ruby on Rails, etc.
