Integrating Environmental Information through Data Warehousing with Data Quality Assurance

Abstract

This paper presents a comprehensive data warehouse framework for integrating environmental information. The proposed framework may serve as a platform and provide appropriate mechanisms for retrieving and gathering environmental data from various sources. For ensuring the quality of data in the environmental data warehouse, we introduce a four-phase process to ensure data quality while performing information integration. Overall data quality conditions can be identified and relevant information can be provided for determining whether the data meet “fit to use” criteria and whether they need to be improved. Accordingly, users may filter the data retrieved from the warehouse based upon various quality requirements.
