"To understand the approach to performance tuning complex SQL queries, the first step is to break down the query structure into smaller parts and identify heavy operations such as joins and aggregations."
"Analyzing the execution plan helps in identifying which parts of the query consume the most resources. Tools like EXPLAIN or SQL Server Execution Plan can be invaluable for this analysis."
"When optimizing indexes, it's crucial to create or modify them on columns that are used in JOIN, WHERE, and ORDER BY clauses. Composite and covering indexes can greatly enhance performance."
