Mike Biensen is currently the business intelligence leader of a major project at Celanese, recently featured in CIO magazine, to move all SAP and other legacy systems to one SAP instance. Benefiting from data warehousing best practices learned prior to his experience with SAP's Business Warehouse, Biensen is implementing this system utilizing a hub-and-spoke architecture. Operational and other source data goes through a data hub where integration and business rule resolution occurs before going to the spokes (e.g., data marts or external systems). He can be reached at email@example.com.
