Which of the following life cycle modeling activities establishes service relationships and message exchange paths?

Service-oriented logical design modeling is the phase in the Service-Oriented Architecture (SOA) lifecycle where abstract business requirements are translated into a detailed, technology-agnostic blueprint for services. This activity explicitly defines the service contracts (interfaces), message structures (data exchange formats), and interaction protocols. By defining these elements, this phase formally establishes the functional relationships between services and the specific paths through which they will exchange messages to fulfill their roles within the architecture. It is the crucial step that bridges high-level conceptual models with the concrete details needed for implementation.

B. Service-oriented conceptual architecture modeling: This is a high-level, strategic phase that defines the overall vision, principles, and major components of the SOA, not the detailed interaction paths between specific services.
C. Service-oriented discovery and analysis modeling: This is an earlier phase focused on identifying and analyzing business processes to discover candidate services. It determines what services are needed, not how they interact.
D. Service-oriented business integration modeling: This phase focuses on composing and orchestrating already designed services to implement end-to-end business processes, which occurs after the fundamental relationships and paths have been established.
