The number of elements that affect query tuning is enormous: table structure, indexes, optimizer behavior, and the SQL text itself are just a few of them. This session will go into depth with specific examples of SQL tuning based on real-world experience. Together with the audience, he will identify a problem, analyze it (from understanding the schema and application logic to looking at the object structure and SQL text), and fix it while learning techniques and some best practices for performance tuning.
