ImpressionModel
extends Model
in package
Model used to keep track for analytic and user experience activities that users carry out on a Yioop web site. For analytics things that might tracked are wiki page views, queries, query outcomes. For UX things that the impression model allows is to keep track of recent group a user has visited to provide better bread crumb drop downs, make the manage account landing page list more relevant groups, determine start of whether a media item has been watched, completely watched, etc.
In terms of how things are implemented in the database. The tables ITEM_IMPRESSION and ITEM_IMPRESSION_SUMMARY contain the raw statistics of activities. If differential privacy is in use then ITEM_IMPRESSION_STAT keeps track of fuzzified statistics.
