Raven accounts

The total number of accounts in the Raven database, the number of accounts available for use, the number of 'active' accounts (i.e. that have been used at least once), and the number of active accounts coresponding to 'current' staff and students of the University. The significant drop in the total number of accounts in June 2011 represents a reduction in the period for which cancelled accounts are retained but not deleted. A significant change occured in mid-2013 from which time Raven accounts have not been canceleld when someone leaves the University (introducing the destinction betwen 'current' and 'non-current' accounts).
