I&#039;m just about to start defining a back-end database for a CMS system. This system will be used to manage multiple sites, users and files and could potentially be huge.<BR><BR>I&#039;m toying with the idea of using GUIDs {AE4715AB-0BC1-4D77-A403-FDEB1A7FFDE9} to track pages etc, and have found articles both praising and condeming their usuage.<BR><BR>Does anyone have an opinion? Are using GUIDs a good way forward?
