About
- Purpose: Records the current value of one user's rating of a given answer (which in turn is tied to a specific question. These are the values which are aggregated to calculate the voting results for each question.
- Rules:
- Any answer may have zero or more ratings.
- Each user sets the value of their rating for each answer, and can change that rating at any time.
- Changes to ratings are logged in the rating log.
History
- 2013-01-09 Removed the "ID_Proxy" field; see rating_log for explanation; added unique key: one rating per answer per user; added WhenEdited, QtyEdits
- 2013-08-05 Designed new version for integrating with PostFerret (added ID_Atom, removed redundant fields) but decided not to implement yet, because value is not clear. Ratings already keep a separate log, and would we ever want to rate a rating? (...or do any of the other things that integration would enable)
