A Data Warehouse is defined as a time variant set of non-volatile data. This can be easily related to temporal database concepts (i.e. a database supporting Valid Time and Transaction Time is known as a bitemporal database). In this paper we analyze and compare the performance of four different bitemporal storage structures (i.e. Backlog based, Tuple timestamped, and Attribute timestamped against Current/Historical which consists of a Current table that reflects current data and a set of Histori...
