FlexSimpleStats
FlexSimpleStats tracks semantic usage statistics within my simulators - what users actually do with them. These days, one can use Google Analytics for this, but SimpleStats predates GA by years. The server side of SimpleStats is implemented in PHP and MySQL, called by client-side Java, Flash, or Flex. This tool browses and charts CourseWare historical usage data, back to January, 2004. Originally implemented in Flash, now in Flex.
