Sample text

During the execution of a business process, participants perform actions. Each action may have a number of input and/or output objects that can be in different states. The same type of objects may occur in several DADs. For example, in the sample business model, objects of the BOOK type are used in the Borrowing and Returning process, as well. The total set of different types of objects in the whole system is given with O = Oi , where Oi is the set of different types of objects in business process represented by DADi .

Example. Consider 2-dimensional sample data presented in Fig. 1. For each data point, star neighborhood is created (Fig. g. {A9,C11, B6,C8} for point A9, and then sorted with respect to the spatial feature and instance id. The final set {A9, B6,C8,C11} constitutes an ordered neighbor relationship between the objects. Step 2. Generate the iCPI-tree of the set of spatial ordered neighbor relationships - from the set of ordered spatial neighbor relationships, the iCPI-tree is iteratively created. Example.

Finally, total set E of classes in the target CDM is E = E P ∪ E O ∪ E A . 1 Existing objects are objects that are not created in the given business process, but in some other process. For example, in the sample business model, objects of the Book type are existing objects in the Borrowing process (each object of the Book type is generated in the BookPurchasing process, but not in the Borrowing process). 2 Automated Generation of Associations We distinguish two different kind of class associations in the target CDM: (i) participant-object associations (associations between classes representing participants and objects), and (ii) object-object associations (associations between classes representing objects).
