Which of the following term is best defined by the statement:"When one object invokes another independent object, a message is passed between the two objects." ?
Correct answer: C. Data couple
- A. Control couple
- B. Application object
- C. Data couple
- D. Database object
Explanation
When objects communicate by passing information in a message, the interaction is treated as data coupling when the message carries data rather than control instructions. Control coupling would involve passing information that directs the other object's execution path.
