Tapahtumalähetin
Tapahtumalähetin, often translated as Event Transmitter, is a concept and a system used in software architecture. It facilitates the communication between different parts of an application or between separate applications by broadcasting events. When a significant occurrence happens within a system, such as a user action, data update, or an error, an event is "sent" or "transmitted" by the source component. Other components that are interested in this particular event can then subscribe to receive these transmissions and react accordingly.
This pattern is a key component of event-driven architecture. It promotes loose coupling, meaning that the components
In practice, Tapahtumalähetin can be implemented in various ways. It might be a simple in-memory message bus
