What is this?

Dashboards need fast aggregates via ADO.NET against curated tables/replicas, refreshed on a schedule.

Why should you care?

ShopNest ops wallboards die if they query raw OLTP detail forever.

See it live — copy this example

Use a .NET console or API project with SQL Server LocalDB. Run dotnet run after pasting.

cmd.CommandText = "SELECT Status, COUNT(*) FROM OrderStatusSummary GROUP BY Status";
// OrderStatusSummary maintained by job/trigger

What happened?

Summary tables or warehouse.
ADO.NET reads summaries.
Refresh jobs update them.

Practice next

Create summary table.
Job refresh.
API reads summary.
Add GMV column.
Index Status.

Remember

Read summaries. Schedule refresh. Short cache.

ShopNest ops board

Wallboard reads OrderStatusSummary.

Outcome: Live board without OLTP meltdown.
