The Event Management is a messaging management component that is responsible for processing events as they happen from components. Processing of record of activities include modelling event messages, syntax validation and formatting of event messages and sending/receiving messages between components (consumer/producer). The Event Management component supports different patterns of usage, including Event notification (subscription), Event-sourcing (representational state changes) and Event-carried state transfer (including data needed to perform further processing). The Event Management component should include functionality providing a centralised CQRS queryStore for all components that implement event-sourcing with event carrier state transfer.
