This pattern has a broad field of application. It is useful whenever dealing with events with a duration – events that have a start date and an end date. The event is considered to be in progress between the two dates. For example, an order is considered open in all the dates between the order date and the delivery date. With the same technique, you can compute the active subscriptions, the open contracts, and other similar metrics.
Students have access to a private discussion area where they can interact with the instructors asking questions related to the lectures and the exercises.
