Point of view in the object model

Question

We have two types of domain: users and locations.

We have a LocationRepository: GetUserLocations () method.

Existing implementation:

var user = UserRepository.GetUser(userId);
var locations = LocationRepository.GetUserLocations(userId);

For me, it makes sense to retrieve the locations associated with the user from the user type ie:

var user = UserRepository.GetUser(userId);
var locations = user.GetLocations();

I think the last implementation is read more cleanly and, as an API client, I have to deal with fewer types (i.e. LocationRepository is not required). On the other hand, there will be more code to support as I need to write a “facade” in the LocationRepository.

Should I work on my instinct and create a facade in the User type in the LocationRepository, or should I be satisfied with the status quo and live with a sequence diagram that "feels" me wrong (for example, finding location information feels that it is being extracted from the wrong "points of view" )?

Answer 1

I would come closer to this in terms of maintainability. I agree that doing this using the facade on the LocationRepository “feels good” and is likely to make the code more readable.
