Document Type



A web document snapshot is a point-in-time capture of its code and the resulting presentation of executing the code. It is used as a way of electronically preserving historical information published in web documents enabling an organization to audit a web document’s contents at a point in the past and perform business analyses with historical information recorded in it. It is also an archived copy of a web document when it is changed. This research develops a system to deliver snapshots of a web document’s static and dynamic contents when it is requested. The system consists of a Database Snapshot Manager for providing database snapshots and a Web Document Snapshot Manager for providing web document snapshots. Algorithms supporting the two managers are presented.
