A content management system is a software application, usually a web application, which makes it possible for people to easily publish documents and data on the internet without any technical knowledge (content management). CMS is also used as abbreviation, to the English content management system (content management system). A functionality of a CMS is that data can be entered without layout (as plain text), while the data is presented to visitors with a layout by using templates. A CMS is especially important for websites whose content requires regular updating, and the content is presented to visitors in a fixed layout. Most large companies now use a CMS for their website. A well-known variation on the CMS is, for example, the weblog.
This means that the owner / manager of a website does not have to deal with the layout, but only with the content. The designer ensures that all content is displayed as designed by the web designer.
