What is content management?
It’s basically a system that houses and maintains online content, ranging from a simple blog right up to fully featured web portals and E-commerce websites. All the various content strands that make up a web presence - blogs, websites, articles and other media - are controlled within the CMS.
A popular example of a CMS is Wordpress, which started life as a blogging platform and has broadened its functionality to provide static page websites and - through the use of add-ons (plug-ins) it can provide more specific functions such as membership and commerce sites.
