Which of the following statements is false?

The correct answer is B. Services are designed to increase the need for integration. Option B is false because service-orientation is specifically designed to reduce the need for integration by making services loosely coupled, reusable, and interoperable - the entire point is to minimize integration complexity, not increase it.

Explanation

Option B is false because service-orientation is specifically designed to reduce the need for integration by making services loosely coupled, reusable, and interoperable - the entire point is to minimize integration complexity, not increase it.

Why the distractors are correct (and therefore not the answer):

  • A is true: a service is precisely defined as a unit of logic that has had service-orientation principles applied to it.
  • C is true: services are the core building blocks of service-oriented architecture (SOA) solutions.
  • D is true: a service composition is, by definition, a set of coordinated services working together.

Memory tip: Think of "service-orientation" as a simplification strategy - it exists to cut integration complexity, not create more of it. If an answer says services make things harder or more complicated, it's almost certainly false.
