A. B. C. D.A.
The service-oriented logical design modeling establishes service relationships and message exchange paths.
It also addresses service visibility and crafts service logical compositions.
The correct answer to the question is A. Service-oriented logical design modeling.
Service-oriented architecture (SOA) is an approach to software development that focuses on creating services that are loosely coupled and independently deployable. In an SOA, services interact with each other to achieve a particular goal. The life cycle of an SOA involves several modeling activities, each of which serves a specific purpose.
Service-oriented logical design modeling is a modeling activity that establishes service relationships and message exchange paths. During this phase, developers create a logical model of the system, which includes the services, their interfaces, and their dependencies. The goal of this modeling activity is to define the relationships between the various services in the system and to establish the message exchange paths that they will use to communicate with each other.
The logical design model is created by analyzing the requirements of the system and the services that will be used to implement it. Developers identify the key services and their interfaces, and then define the message exchange patterns that will be used to communicate between them. They also establish the dependencies between the services, identifying which services rely on others to function correctly.
Once the logical design model is complete, it is used to guide the development of the physical implementation of the system. Developers use the model to create the necessary code and configuration files to implement the services and their interfaces. They also use the model to test the system and to verify that it is functioning correctly.
In conclusion, service-oriented logical design modeling is the modeling activity that establishes service relationships and message exchange paths. This activity is essential to the development of an SOA and ensures that the services in the system can communicate with each other effectively.
