When the application and database are one to one, then Entity Framework can use migrations to become the source of truth. Database changes are made within the application and migrated to the database through Entity Framework. This solves the duplicated information problem and ensures the database and code always match. However it isn't always the case that the application can drive database changes. Often the application is hitting multiple databases, or databases that belong to other systems. This means that the application has to be updated when database changes are made. Re-scaffolding the data models with the database changes regularly means that the models are generated…
