{"version":"1.0","type":"rich","title":"ROCBNDbContext","description":"This example shows a read-only database context for the ROCBN domain, mapping three entities—`Entities`, `EntityBusinessActivities`, and `EntityOtherInformation`—to their corresponding tables in the `ent` schema using Microsoft's Entity Framework Core. The code defines table mappings, indexes on foreign-key columns, and row-version concurrency tokens. It also overrides `SaveChanges()` to throw an exception, enforcing a read-only access pattern. Relationships include a one-to-many from `Entity` to business activities and a one-to-one link to other information, both configured via the `ModelBuilder` API.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-c0b5e2fb927a650c32485f8a7ab23813?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
