👉 Query math, also known as query optimization or query analysis, is the process of analyzing and improving SQL queries to enhance their performance. It involves understanding how a database engine processes a query, identifying bottlenecks, and suggesting modifications to the query structure or execution plan. This can include rewriting subqueries into joins, optimizing index usage, reducing the amount of data scanned, and minimizing the number of operations. The goal is to ensure that queries run efficiently, even on large datasets, by leveraging database-specific features and best practices. By applying query math techniques, developers can significantly improve the speed and resource utilization of their database operations.
