"Since the introduction of the cost-based optimizer in the initial release of DB2 in 1983, IBM has continually evolved optimization technology. In recent years, DB2 for z/OS has extended support for complex relational data structures such as star schemas as well as access path visualization with Visual Explain. In DB2 for z/OS, Version 8, Statistics Advisor was added to Visual Explain to provide a rich client for tuning queries. IBM plans to continue to extend optimization through expert based query and workload analysis, server enhancements and a workload history warehouse."

Easing the Cost of Compliance
par James Pickel (IBM SVL)

"The Sarbanes-Oxley Act and other regulations require corporate executives to provide and ensure increased levels of financial and operational discipline. To help comply with this law, most enterprises are now implementing measures that cross financial reporting and processes that impact internal business and computing operations. Privacy regulations, such as those imposed by HIPAA, create operational discipline on a company's IT operations that have a similar impact. This article describes how new features in DB2* V9.1 for z/OS* can help ensure compliance by allowing better user accountability, providing end-to-end identity controls and improved auditing capabilities."
