Abstract

A data warehouse (DW) provides information from external data sources for analytical processing, decision-making, and data mining tools. External data sources are autonomous, i.e. they change over time, independently of a DW. Therefore, the structure and content of a DW has to be periodically synchronized with its external data sources. This synchronization concerns DW data as well as schema. Concurrent work of synchronizing processes and user queries may result in various anomalies. In order to tackle this problem we propose to apply a multiversion data warehouse and an advanced transaction mechanism to a DW synchronization.
