CMS is an acronym of  Content Management System and is widely used to describe software that is put in place to enable people to update and manage their own websites.

A CMS usually stores the content used on web pages in an online database which can then be added to and edited by members of the organisation as part of the publishing process.

Different people in an organisation can be assigned different levels of access to a CMS. E.g. some people could be given the ability of adding new pages whereas others may only be able to edit or approve changes to existing pages.

Many off the shelf software CMS packages exist or you can ask a web development company to create a bespoke package to suit your specific needs or business sector.
