WHY DATABASE QUERY TUNING MATTERS

In modern enterprise applications, slow queries mean slow business. Database Query Tuning (also called SQL Performance Tuning or Query Optimization) is the art and science of making queries run faster, use fewer resources, and scale reliably. For businesses running large transactional systems, analytics platforms, or cloud databases, skilled query tuners save time, infrastructure cost, and deliver better user experience. That’s why demand for query tuning specialists is high in India’s IT industry — from startups to global product companies and large services firms.
