A content management system (CMS) is a computer database that allows publishing, editing and modifying content as well as maintenance from a central interface. The CMS interface enables you to easily edit and update your website without needing to know how to code the website.
There are numerous options for a content management system when developing a new website. Factors that determine the best option are how advanced you need the CMS to be, what language it is built in and who is going to be using it. The best options come down to usability, flexibility, and expandability.
