Building Dashboards with MySQL Data: Best Practices

A good dashboard is a fast query wearing a nice interface. The real work happens in MySQL: shaping data so the BI layer can stay simple, quick, and correct.

Key Points

• Create dedicated reporting views so dashboards never touch raw tables
• Pre-aggregate to the grain you display (daily/weekly summaries)
• Define KPIs in one view — every chart reads the same logic
• Index the date and filter columns dashboards use most
• Schedule refresh windows off-peak; cache where the BI tool allows
• Version your view definitions — dashboards break silently when SQL changes
