Final answer:
In an event-driven architecture (EDA), all of the above statements are correct. EDA handles each business event individually, reduces delays in processing, and sends event notifications to middleware.
Step-by-step explanation:
In an event-driven architecture (EDA), all of the above statements are correct.
A. Each business event is handled individually, meaning that the system responds to a specific event or trigger instead of following a predetermined sequence of steps.
B. Real-time processing reduces delays in business processing, allowing events to be processed as they occur.
C. An event notification is sent to the middleware, also known as 'publish' or 'send', where it can be further processed or acted upon.
Overall, EDA offers flexibility, responsiveness, and reduced processing delays by handling events individually and leveraging real-time processing.
Therefore, the correct answer is D.all of the above.
