WebPartPersonalization uses this method to delete personalization data from the database when a Web site user chooses to reset Web Parts data on a page. If username is non-null, data with the User scope data is deleted; otherwise, data with the Shared scope is deleted.
The SqlPersonalizationProvider object automatically updates the LastActivityDate column in the aspnet_Users table each time user-specific personalization data is deleted from the database in the context of a page request. This behavior allows other ASP.NET features to use the LastActivityDate value when managing stale data records as well as determining recent user activity on a site.
