实体框架核心如何为模型创建参考表

Question

I have been using SQL tables for referencing static data, for example in one of my apps a technician has a one-to-many relation with a clients table.

Basically what I want to do in SQL is this, so instead of dealing with strings I deal with ints as byte or tinyint which takes less size on disk since Clients are always static and it's rare to add new ones.

 | Technicians |    |            Clients              |   | ClientsRef |
 |     Id      |    | Id | ClientRefId | TechnicianId |   | Id  | Name |

My problem is to do this in EF Core 2.2, how do I create this static data? I read about using enum but how can I access that data in SQL Server after?

public class Technician
{
    int Id { get;set; }
}

public class Client
{
    int Id { get;set; }
    int Technicianid { get; set; }
}   

Answer 1

This:

public class Technician
{
    int Id { get;set; }
}

public class Client
{
    int Id { get; set; }
    int TechnicianId { get; set; }
    public virtual Technician Technician {get; set;}
    public string Name { get; set; }
}

Should be all you need. There's no need for any other tables or keys in the model.
