ShalomCloud now captures an audit trail of changes and deletions to certain critical portions of data–initially, Yahrzeits, Families, and Individuals.  This video shows how it works:

ShalomCloud Audit Trail from Norman Snyder on Vimeo.

In a nutshell, the audit trail captures when the change occurred, by whom, what changed, a version number, and the content of each changed field both before and after the change.

On deletions, it captures the entire record that was deleted–thus enabling you to re-add a record if it were inadvertently deleted.
