eseményközpontú

Eseményközpontú is a Hungarian term that translates to "event-centric" or "event-driven" in English. It describes a design philosophy or approach where the primary focus is on the occurrence and handling of events. In software development, an event-centric architecture is characterized by components that communicate with each other by producing and consuming events. When something significant happens within a system, it generates an event, which is then broadcast to other interested components. These components can then react to the event in a predefined way.

This paradigm is often contrasted with traditional request-response models. Instead of one component directly requesting information or action from another, in an event-centric system, components observe events. When an event occurs that matches their interest, they act upon it. This loose coupling between components is a significant advantage, as it allows for greater flexibility and scalability. Systems can be more easily extended by adding new components that listen for existing events without needing to modify the original event-producing components.

The concept finds applications in various domains, including user interface design, where user actions like clicks or key presses are events that trigger system responses. It is also fundamental to many modern distributed systems, microservices architectures, and real-time data processing pipelines. The core idea is that the flow of control and data is dictated by the sequence of events rather than a rigid, predetermined order of operations.
