[basex-talk] What's the diff between Database and collection

Hi, What's the diff between Database and collection? I think there are same in baseX, am I right? And how to query by a document name? Following are steps of my testing: 1: loaded some xml files form a directory: d:\data\org-*.xml 2: query by doc('org-100525.xml') and got File or directory "D:/Program Files (x86)/BaseX701/bin/org-100525.xml" not found message. 3: because after loaded xml, directory: d:\data\org-*.xml was removed. I can't query by doc('d:\data\org-100525.xml')

Thanks, Edward
