Which term describes a system that provides data interoperability and quality of service in distributed networks?

• A. Energy (Industries and Sectors)
• B. Healthcare (Industries and Sectors)
• C. Data Distribution Service (DDS)
• D. Logistics (Industries and Sectors)

Answer: (C)

Data Distribution Service (DDS) is a middleware standard that enables data interoperability and quality of service in distributed networks. It uses a data-centric publish/subscribe model, so components from different vendors can exchange information without tight coupling. DDS defines standardized data models and communication interfaces, which helps disparate systems understand and utilize the same data. Beyond interoperability, DDS offers a robust set of quality-of-service policies that control how data is produced, transmitted, and stored—covering reliability, durability, deadlines, latency budgets, liveliness, history, and more. This lets developers tailor data delivery to the real-time needs of the network, ensuring timely, reliable communication even as the system scales or networks change. The other options are industries or sectors, not a system designed to provide interoperable data exchange with QoS features.
