Ralph Kimball – The Data Warehouse ETL Toolkit

The Data Warehouse ETL Toolkit shows data warehouse developers how to effectively manage the ETL (Extract, Transform, Load) phase of the data warehouse development lifecycle. The authors show developers the best methods for extracting data from scattered sources throughout the enterprise, removing obsolete, redundant, and innaccurate data, transforming the remaining data into correctly formatted data structures, and then physically loading them into the data warehouse.   źródło opisu: http://eu.wiley.com/WileyCDA/WileyTitle/productCd-1118875184.html źródło okładki: https://www.amazon.com/gp/product/B006JAWFE4/ref=s…»
