Enterprise Data Warehouse Design Method using SAP Net Weaver Business Warehouse

Data warehouse is an informational system optimized to store large amounts of data and create analytical reports for decision support. Principles of classic data warehouse architecture cannot be applied for enterprise data warehouses (EDW) based on key performance indicators (KPI). In this article we offer a methodology that takes into account the KPI, we review and justify the enterprise data warehouse design technique using SAP NetWeaver Business Warehouse. Our step by step guide to data warehouse design features SAP LSA (Layered Scalable Architecture) standard. It consists of 7 layers, each serving the particular purpose of EDW functionality. LSA is flexible; it can be easily modified to fit various kinds of business processes. We provide a practical example of an EDW design for customs department of an oil and gas company.
