Sample text

In other words, the status of customer POs, work orders and material POs have to be updated after every step in the process. In both cases, the end-result is that the business process model is “polluted” with tasks whose sole purpose is to move data between the process execution layer and the system(s) that manage the key entities of the BTO process, namely the customer PO, work order and material PO. In this setting, what SOAs achieve is that they facilitate data access. They make it easier for developers to implement the necessary interactions between the process layer and the data and business logic layer, but they do not obviate nor reduce the need for coding such interactions and weaving them into the process model.

Thereafter, tokens containing s’ are deleted. This processing of tokens containing unstable states is repeated until all existing tokens have reached stable states again. When this happens, the DecisionModule gets the control again and decides which tokens are transferred next. Consider for example the tokens (3/s6, 3/s6), (5/s6, 5/s6), and (7/s6, 7/s6) representing answers to the sub-query //self::b. If we fire the transitions from state s6 to state s3 in bottom-up direction, this removes and transfers the tokens having state s6 as their start state, and it will stop, when all tokens are either deleted or transferred to tokens having state s3 as their start state.

The queries that we used are shown in Table 2. 36 M. Benter, S. Böttcheer, and R. Hartel Table 2.
