Content Management leaves the responsibility for most maintenance in the hands of the site owner - not the web professional.  There are many different types and many different uses for CMS.

Site Management - Any entire site can be converted to this such as panamaeagle.com or akfitto.com or a part of a site for those pages you need to change often such as marvesta.com and sidmalkin.com . You can't see the cms at work but they save the owners time and money! The CMS used here is not available anywhere else by the way! Delia's own. Now it's integrated with Xinha. See more information about the xinha editor here.

Article Management - used for posting of articles by the owner or allowed guests/registered users.  See these sites for examples: avoc.info,nobacco.org.

News Management - for simple posting of short news items - nobacco.org

Clip Art or Photo Management - clip art catalogs, artist portfolios and even a teacher appreciation site!  oconeeteachers.com, delia's portfolio, plattbrooks.com.

Calendars & Event Management - Handle your own calendar or allow others to have their own calendar on your site.  newlifeapostolic.com.
