Final answer:
The question pertains to Event-driven architecture (EDA), which is an approach where business events cause messages to be sent between independent software modules, fostering scalability and responsiveness in enterprise systems.
Step-by-step explanation:
The question identifies an approach to designing and building enterprise systems where business events initiate the sending of messages between software modules through middleware, and these modules are completely unaware of each other. This description aligns with the term Event-driven architecture (EDA). EDA enables the segregation of software components to respond independently to events, which are significant changes in state. This architectural style is critical as it helps in creating highly scalable and responsive systems. It is often used in complex automated systems where human software interactions and decision-making processes are supported by the software system.
Furthermore, this concept relates to the process of engineering design, where an idea transitions from a design concept to a detailed design, which Eppinger and Ulrich (2003) refer to as the development of the design architecture. A design architecture assigns functional elements to the building blocks within a product, and in the case of software, this would involve deciding how different modules interact in an event-driven manner.
