Common advantages of a CMS:

Published October 4, 2010 | By K. Solomon

Decentralized maintenance.
Based on a common web browser. Editing anywhere, anytime removes bottlenecks.
Designed with non-technical content authors in mind.
People with average knowledge of word processing can create the content directly. No HTML knowledge needed.
Configurable access restrictions.
Users are assigned roles and permissions that prevent them from editing content which they are not authorized to change.
Consistency of design is preserved.
Because content is stored separate from design, the content from all authors is presented with the same, consistent design.
Navigation is automatically generated and adjusted.
Menus are typically generated automatically based on the database content and links will not point to non-existing pages.
Content is stored in a database.
Central storage means that content can be reused in many places on the website and formatted for any device (web browser, mobile phone/WAP, PDA, print).
Dynamic content.
Extensions like forums, polls, shopping applications, searching, news management are typically modules.
Cooperation.
Encourages faster updates, generates accountability for authored content (logs) and cooperation between authors.
Content scheduling.
Content publication can often be time-controlled, hidden for later use or require user login with password.
