In web terminology, CMS stands for “Content Management System”. It describes a method of managing website design, development, and more importantly to the end user, the website's content, workflow, and collaboration.
CMS are online software installations, typically installed on the site owner's hosting server and require initial and often ongoing configuration.
CMS have effectively revolutionized the way people think about, and control content on websites.
CMS allow designers and developers an effective and quick way to easily modify site design and functionality. This almost always means that everything you need or want to do with your website will be cheaper and easier than ever.
From Wikipedia, the free encyclopedia - Web content management system
A Web Content Management System (WCMS) is a software system that provides website authoring, collaboration, and administration tools designed to allow users with little knowledge of web programming languages or markup languagesto create and manage website content with relative ease. A robust WCMS provides the foundation for collaboration, offering users the ability to manage documents and output for multiple author editing and participation.
- Most systems use a Content Repository or a database to store page content, metadata, and other information assets that might be needed by the system. A presentation layer displays the content to website visitors based on a set of templates. The templates are sometimes XSLT files.
- A WCMS allows non-technical users to make changes to a website with little training.
A WCMS typically requires a systems administrator and/or a web developer to set up and add features,Wikipedia - Web content management system
