In this paper, we describe a taxonomy of bi-temporal events in order to show how bi-temporal databases based on a Bi-temporal Object State and Event (BOSE) model are able to cope with non-destructive updates and managing error corrections in bi-temporal databases. Our proposed scheme classifies bi-temporal event types according to their roles in maintaining bi-temporal database state histories. We classify these events into start, transitional and final bi-temporal event types. Transitional bi-temporal event types are further classified into corrective, amended and other user-defined types.
We demonstrate how this taxonomy can be used in designing bi-temporal database systems based on our proposed Bi-temporal Object State and Event Modelling Approach (BOSEMA) and show a generalized internal representation of this taxonomy in a bi-temporal database schema.
