Computer forensics cannot always get the data back. Television crime shows greatly exaggerate the capabilities of computer forensics. It depends on what format the data was in, how the data was deleted, and what has happened on the computer since it was deleted. Even in the cases where it is possible, it requires taking the system offline (making it unavailable for other people to use), requires specialized software, can take days of work, and often can retrieve only part of the data. This is not feasible in a working database like your library network.

Millennium cannot do that. The only internal mechanism in Millennium to prevent records from being deleted is by controlling who can perform deletions. There is no mechanism in Millennium to notify either the person deleting or the owner of a review file that a record being deleted is in a review file. It is not feasible for someone deleting records to manually check every review file to see whether a record is in one of them.
The only way to control deletions is by careful training, limiting who can delete data, and establishing policies on when and how data are deleted. This is something between you and the consortium, but it sounds like Minuteman has established policies and is following them.
