Is it possible to have "sub-models" with Entity Framework?

I was wondering if it was possible to have "sub-models" within Entity Framework entity models?

For example, this:

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

   public UserPermissions Permissions { get; set; }
}

public class UserPermissions
{
   public bool CanRead { get; set; }

   public bool CanWrite { get; set; }
}

Then in the actual table, there would be these columns:

Id
CanRead
CanWrite

or even with a prefix, like that:

Id
Perm_CanRead
Perm_CanWrite

Is that a thing? Is there an alternative you may know of? Or is my best bet to use a base/abstract class like public class User : UserPermissions { }?

>Solution :

Yes, this is possible in EF Core by using owned entities. The docs explain it pretty well but, for example, you can have this:

[Owned]
public class StreetAddress
{
    public string Street { get; set; }
    public string City { get; set; }
}

public class Order
{
    public int Id { get; set; }
    public StreetAddress ShippingAddress { get; set; }
}

Or if you prefer using the fluent API:

modelBuilder.Entity<Order>().OwnsOne(p => p.ShippingAddress);

Which will give you a table like this:
