data collection

Does anyone have any policies they can share in regards to retention of data obtained in part from student activity through your website that goes towards generation of a grade?

Abstract: This case study describes two ways to push data collected within a Flash activity into the Drupal database. The two solutions vary in some important ways: the ability to enable AHAH form submission to avoid page refreshes, the ability to access collected data from Views, the ability to export collected data to a spreadsheet, and of course, ease of implementation. One caveat for both solutions is that they do rely on javascript. The only non-javascript solution I am aware of involves the use of AMFPHP and the Services module. Implementation of these is easy if you are working in AS3. Not so much for AS2.
