<p>First some background. I recently went for an interview and some of the questions asked to me was about Enterprise Content Management. Obviously, I did not have any experience and did not get the offer. </p>

<p>But, it increased my curiosity and tried Internet to get some info on the topic. Wikipedia made me more confused with even more buzzwords. Most of the stuff on the web is marketing related and relevant to specific products like Sharepoint or Drupal etc.</p>

<p>I need some help in understanding more about the topic or the <strong>domain</strong> in simpler terms. What is the requirement to use it? What kind of companies use it? What are the problem areas it tries to address? Any popular use cases? Any places where it looks like a good fit but it is not actually?</p>

<p>Lastly, any good book or articles on the topic without being specific to any product?</p>

CMS (Content Management System) describe systems that are used to manage content :-) as for example Joomla, Drupal, Sharepoint and etc.
Content management means document, records, processes and other information related to your company business management.
Enterprise Content Management, as far as I know is this "Content management" concept applied to a organization. The mainly focus is to Capture, Manage, Store, Preserve, and Deliver content and documents related to the organization.
