Data quality in data warehouse systems: A context-based approach

摘要: Many researchers have presented the need to incorporate and maintain data quality in Data Warehousing Systems. However, there is no consensus research community on how do it. On other hand, loaded into Warehouse come from different sources with levels of quality. Analysis domains these can vary users perceive ways, depending their profile, task be performed, etc. depends multiple factors: sources, performed data, user preferences, Hence, context which will used. For this reason, we present a proposal assess Systems an approach based Contexts.
