Table 4.6 flattens the original database consisting of four tables. The flattened event log is like a view on the complete data set. Alternative views are possible. For example, Fig. 4.11 shows another way to flatten the original database. Now cases correspond to order lines rather than orders. Hence, the root node is order line 112345. This is an order line of order 91245 and three attempts were needed to deliver the iPhone 4G. The times tamps in the Order table have been used to create events associated to order line cases rather than orders. Based on the view sketched in Fig. 4.11, one can generate another event log
