Two builds, one schema, zero faith required. From Table to Twin walks an industrial digital twin's SQL Server and EF Core backbone by hand and from code, then prints exactly where Database First and Code First disagree — for .NET developers who check every table against a live, running console.

One entity. One mapping. Clean context. From Entity to Context shows how to organize enterprise EF Core Code First projects with configuration classes, Fluent API, migrations, indexes, relationships, and a clean DbContext across the NEXUS-1 digital-twin schema.

One database. Seventeen sectors. Fully keyed. From Schema to System maps the complete SQL Server / EF Core data backbone behind the NEXUS-1 digital twin, showing how telemetry, alarms, root-cause analysis, reinforcement learning, compliance, reporting, and audit become one queryable system.
