CMS stands for content management system
CMS is short for content management system, which is a system that manages content, specifically the content of a website. There are many various CMS, the most well-known are WordPress, Joomla, OpenCMS, Drupal and Typo3. In the context of a website a CMS is used to publish and manage content easily on a website, without any prior programming knowledge. A CMS creates a complete website structure with basic system functions such as creating pages and navigation between pages. Content can be added with the help of special web editors or through automated processes and routines.
In addition, a CMS can provide further functions for preparing content such as a picture gallery, or for interaction with the help of contact forms or comment functions in the form of system components or modules.
CMS enables regular maintenance of websites
Summed up, it can be said that a CMS is primarily used to easily manage content on a website and to navigate the site. But a CMS can do so much more. A CMS lets you update the content of a website yourself, the CMS manages images, videos and files so that it is easier for the user to integrate these files into the website. A CMS provides the ability to copy or move the contents to another location.
A CMS is helpful even in relatively small websites – about 20 pages. In even smaller websites that need to or should be updated regularly, a CMS is pretty much a must.
The investment in a CMS is a cost factor: even the fastest web designer will not be able to update a new website in a web presence faster than one person who does not have much programming knowledge can with a CMS.
