Abstrakt

Recently, there is a trend to build data warehousing based on Wide-column stores (WCSs). Different from the relational database systems, each column in a WCS can maintain multiple data versions. In this paper, we study how to maintain the materialized temporal views in WCS with attribute-timestamping model (ATM). As a WCS usually contains a large number of columns, it is preferable to treat an update as an individual class instead of a deletion/insertion pair. For propagating temporal deltas, temporal queries are classified into various types and the corresponding temporal delta propagation rules are defined.
