Contents:
Prefaces -- Introduction -- Some thoughts concerning the term "SQL Tuning" -- Minimum minimorum to the subject "Execution Plan" -- Approaches to formal SQL Tuning -- Bottlenecks in Execution Plans -- Procedure for formal SQL Tuning -- Practical experiences with formal SQL Tuning -- Appendix -- Application of the formal method for analysis of performance issues following Oracle migration.
In: Springer Nature eBookSummary: The target of SQL tuning is the improvement of the existing execution plan. The authors discuss the removal of brakes in the execution plan. Such "brakes" or bottlenecks can be recognized by a formal analysis of the execution plan. For this purpose no data model knowledge is needed. This is especially beneficial for database administrators because they are usually not or insufficiently familiar with the data model. The book presents numerous practical examples with this method.
