The concept of ________ allows real-time data processing systems to respond to events or changes immediately.

Event-driven architecture is a design approach that enables real-time data processing systems to respond to events or changes immediately, without waiting for batch processing cycles. This architecture allows systems to react dynamically to incoming events or triggers, enabling timely actions, notifications, or updates based on real-time data streams. It is well-suited for applications requiring low latency, high scalability, and responsiveness to dynamic environments.
