Description: The Notification Pattern is a design pattern that facilitates the communication of events between components in a system. This pattern allows an object, known as the ’emitter’, to notify other objects, called ‘subscribers’, about changes in its state or the occurrence of specific events. The main characteristic of this pattern is its ability to decouple components, meaning that emitters and subscribers do not need to know each other’s internal implementation. This promotes a more flexible and scalable architecture, as components can be modified or replaced without affecting others. Additionally, the Notification Pattern is particularly useful in applications where multiple parts of the system need to react to events, such as in dynamic user interfaces or messaging systems. Its relevance lies in improving the maintainability and responsiveness of applications, allowing for smoother interaction between different software modules. In summary, the Notification Pattern is an essential tool in software design, optimizing communication and collaboration between components, facilitating the development of complex and efficient systems.
