Abstract
A data warehouse is a large database integrating data from a number of enterprise independent source application databases over a long period of time [8]. A data warehouse is organized around major subjects (entities) of an enterprise and not around its functions. For example, in a banking environment which has two independent source databases, one for savings account functions and the other for chequing account functions, a data warehouse that integrates these two databases has the following basic structure: bt (customised (C), accounttype (A), time (T), balance).
This research was supported by the Natural Science and Engineering Research Council (NSERC) of Canada under an operating grant (OGP-0194134) and a University of Windsor startup grant.
