eseményvezérléssel

Eseményvezérlés, often translated as event-driven architecture or event-driven programming, is a software design pattern that promotes the production of reactive, loosely coupled, and scalable applications. In this paradigm, the flow of the program is determined by events. An event can be anything that the system can detect, such as a user action, a sensor output, a message from another application, or a system status change.

When an event occurs, it is broadcast to a system that handles events. This system, often called an event bus or message broker, then routes the event to any components or services that have registered their interest in that specific type of event. These interested components are known as event handlers or subscribers. Upon receiving an event, an event handler executes a specific piece of logic in response.

The key benefits of eseményvezérlés include enhanced flexibility and extensibility. Because components react to events rather than directly calling each other, they are more independent. This allows for easier modification, addition, or removal of components without impacting the entire system. Furthermore, event-driven systems are naturally well-suited for asynchronous operations and can easily scale by adding more handlers to process events in parallel. This pattern is widely used in microservices architectures, real-time data processing, and user interface development.
