Consider implementing a materialized view or summary table in SQL Server for dashboard data. Pre-aggregate metrics by hour or day instead of querying raw records. For a 6-month date range, you’d query 4,380 hourly records instead of millions of raw records. Refresh the summary table nightly with a SQL job.
