Understanding Event Modeler
Event Modeler is designed as a specialized tool for describing and modeling systems and processes through detailed steps, focusing on the events that change or represent the state of a system. It employs an event-driven architecture approach to outline how systems behave in response to various inputs or actions. Through its methodology, Event Modeler provides a clear, traceable, and systematic way to visualize and understand the flow of information and state changes within a system. An example scenario could involve modeling the process of a customer placing an order on an e-commerce platform. In this case, Event Modeler would detail the steps from order placement, through payment processing, to order fulfillment and delivery, each step marked by a state change (e.g., 'OrderPlaced', 'PaymentProcessed', 'OrderFulfilled') or a view into the system's current state (e.g., viewing the current order status).

Core Functions of Event Modeler
State Change Modeling
ExampleWhen a user places an order, Event Modeler would model this as a 'PlaceOrder' command, leading to an 'OrderPlaced' event, detailing the item, quantity, and customer information.
ScenarioIn an online shopping system, this function allows the tracking of each step in the order process, ensuring the system's state is accurately updated and traceable through each customer interaction.
State View Modeling
ExampleA screen showing a customer's current order status, populated by a read model that aggregates events like 'OrderPlaced', 'PaymentProcessed', and 'OrderShipped'.
ScenarioThis enables customers and administrators to view the real-time status of orders, facilitating better customer service and operational oversight.
Event-Driven Testing
ExampleGiven past events of 'OrderPlaced' and 'PaymentProcessed', when 'ShipOrder' is commanded, then an 'OrderShipped' event is expected.
ScenarioThis testing approach helps in verifying that the system behaves as expected under various conditions, ensuring reliability and correctness of the event-driven processes.
