TAILIEUCHUNG - Oracle Performance Tuning for 10gR2, Second Edition

Tuning of SQL code is generally cheaper than changing the data model. Physical and configuration tuning involves a search for bottlenecks that often points to SQL code or data model issues. Building an appropriate data model and writing properly performing SQL code can give 100%+ performance improvement. Physical and configuration tuning often gives at most a 25% performance increase. | Oracle Performance Tuning and Optimization Edward Whalen SAMS PUBLISHING 201 West 103rd Street Indianapolis Indiana 46290 To my father.
