How I Built a SQL Diagnostic Tool That Works Without Touching Your Database ^{(from DZone)}

pMost developers I've worked with write SQL every day. Very few of them are DBAs. According to the 2024 Stack Overflow Developer Survey — 65,000 developers across 185 countries — database administrators make up just 0.3% of the developer population. The tools built for SQL performance were designed for that 0.3%. I built QueryTuner for everyone else./p pI've spent 13 years as an application archite [...]
