What happens if the GetEmployeeById Aggregate does not return any record?

The scenario where the GetEmployeeById aggregate does not return any record will trigger the RecordNotFound flow. This behavior is designed to enable developers to handle cases where a data retrieval operation yields no results, allowing for a graceful response to users or to execute alternative logic within the application.

The RecordNotFound flow allows the application to manage situations where expected data is missing, providing opportunities to inform the user, log the incident, or raise alternative processes within the application. It ensures that developers can anticipate and handle such situations, leading to improved application robustness and user experience.

Other options involve different types of error handling mechanisms. For example, a DatabaseException flow is typically invoked when there is a problem with the database operation itself, such as a connection failure or a SQL syntax error. The global exception handler would deal with unhandled exceptions that occur throughout the module, but these do not apply when specifically dealing with no records being found. Thus, in this context, the appropriate response is through the RecordNotFound flow, reinforcing best practices in error handling within applications.
