The SnS data model lives in DataMine.Models and represents the database schema used by framework services and host applications. It includes entities for places, clients, contacts, projects, assets, regions, shapes, spaces, and supporting lookup or metadata tables.
DataMine.Models is schema-shaped and generated with EF Core tooling. Generated files should be treated cautiously. Business rules, normalization, validation, and workflow behavior should generally live in services and state classes rather than being pushed into generated model files.
