Show Suggested Answer

Suggested Answer: D

The diagram uses the ArchiMate notation for a goal element and an aggregation relationship. A goal element represents an end state that a stakeholder intends to achieve. An aggregation relationship indicates that a whole is composed of parts. In this case, the goal 'Reduce Expense Ratio from 13% to 11%' is composed of three sub-goals that contribute to its achievement.

Access, definitely. I mean, what else would an application service do with a data object? Stare at it? Nah, it's gotta be Access all the way.

I'm not sure, but I think it might be Composition because the application service may be composed of multiple data objects.

I see your point, but I still believe it's Access because the application service needs to access the data object to perform its functions.

I think it's actually Realization, because the application service is actually implementing or providing the functionality of the data object.

Wait, wait, wait. I'm pretty sure the correct answer is Aggregation. You know, like the application service collects and organizes all the data objects together. Kind of like a digital hoarder, but in a good way.

I believe the correct answer is Realization. It represents how the application service implements or provides the functionality of the data object.

I think you might be mistaken. The relationship type from an application service to a data object is actually Access.

Oh man, this is a tricky one. Let me think... Ah, I got it! It's Realization. The application service realizes the data object, like a superhero realizing their true potential.
