In Fig. 4.10, the root node is an order. In Fig. 4.11, the root node is an order line. Similarly, it is possible to take a delivery or delivery attempts as root node. Moreover, various selections of events can be used, e.g., the three order-related events or the three delivery-related events in Fig. 4.11 could have been left out from the selection. This shows that many views on the original data set are possible, i.e., there are many ways to flatten reality as recorded into a single event log.
