Abstract

EN In this paper we propose a framework for detecting changes in external data sources (EDSs) and propagating them into a multiversion data warehouse (MVDW). The architecture of our prototype MVDW uses an operational data store (ODS) as a buffering layer between EDSs and a MVDW. The functionality of the ODS that we developed is responsible for detecting structural changes in external data sources and creating the set of MVDW modification operations automatically. The operations can next be applied to a new or existing data warehouse version. Changes in data sources that are to be detected and the way they are to be propagated into a data warehouse are defined by a management software, also discussed in the paper.

Błąd w tytule – powinno być "warehouse" zamiast "wareshouse".
