Because it isn't anonymous.

Case in point, I'm writing a website for a relatively innocuous data gathering site for a non-profit related to providing services, assistance, etc., for pregnant/nursing moms. The client asked me to have some of the data gathering to be actually anonymous (in this case, simple survey questions, like how valuable did you find the services and what was your experience at group meetings.) To make the data actually anonymous, I have to make sure that the data is stored in a way that is truly anonymous -- again, trivial in my case but the underlying table cannot have any references to the participant that answered the survey. Technically, even a timestamp, necessary for doing reports for a specific time period, could be used to associate the anonymous data with other tables that do maintain participant information, especially if there is a timestamp in those tables that could be used to correlate when the records were inserted into the database.

Most ORM's will nowadays automatically add a "created at" and "updated at" timestamp behind the scenes, or worse, introduce a foreign key without my explicitly specifying an FK. In my particular case, I'm not using a 3rd party ORM (preferring my own orm-less solution), so I know exactly what the database is persisting. Even so, the temptation was there to associate the anonymous data with the participant internally but just not reveal that association through any user-accessible data mining / reporting features. But then, the data isn't really anonymous, is it?

The point being, unless the developer things very carefully about how to ensure that the data is truly anonymous, it probably isn't.

Marc

So,
