Audit Log
A very good way of tracing back a problem is for the system to keep an audit log.
This means the computer will record every important event in an 'audit file. It records who saved what and when. Who deleted records or changed them. For example an audit record may look like this:-
User: bigears233
File: TheMostImportantFile.doc
Changed: 3rd January 10:15am
(or Deleted, or Saved).
