This article aims to describe some of the data design and data workload management features of Azure SQL Data Warehouse. The information generated in this process is used by the warehouse management process to determine which aggregations to generate. Big Amounts of data are stored in the Data Warehouse. During the physical design process, you convert the data gathered during the logical design phase into a description of the physical database structure. an ODS will not be optimized for historical and trend analysis on huge set of data. Ralph Kimball's bottom-up approach proposes to create a business matrix which should contain all the common elements (that are used by data marts such as conformed\shared dimension, measures, etc.) Selection of right data warehouse design could save lot of time and project cost.
