You’re not alone when moving from a layered structure to systems containing several independent processes. One component may require the result of another, while repeated direct calls can gradually create a complicated network of dependencies. Further difficulties appear when information is processed asynchronously, events arrive in different orders, and individual operations may end with an exception. Without defined interaction rules, following data movement, reviewing system behaviour, and replacing separate components becomes more difficult.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cb\u003e2.

You will examine ways to separate the source of an event from the components that respond to it. The materials explain how to organize asynchronous operations, combine their results, and handle exceptions at different stages. Dedicated modules cover event logging, state control, and the testing of communication between components. The final project combines layered structure, repositories, services, events, and concurrent tasks within one integrated system.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cb\u003e3.
