Enterprise applications are presently built on a 20-year old data management infrastructure that was designed to meet a specific set of requirements for OLTP systems. In the meantime, enterprise applications have become more sophisticated, data set sizes have increased, requirements on the freshness of input data have been strengthened, and the time allotted for completing business processes has been reduced. To meet these challenges, enterprise applications have become increasingly complicated to make up for short-comings in the data management infrastructure. To address this issue we investigate recent trends in data management such as main memory databases, column stores and compression techniques with regards to the workload requirements and data characteristics derived from actual customer systems. We show that a main memory column store is better suited for to days enterprise systems, which we validate by using SAP’s Net Weaver Business Warehouse Accelerator and a realistic set of data from an inventory management application.
