Method and system for matching operation examples in model execution of BPMN (Business Process Modeling Notation)

Abstract

The invention discloses a method and a system for matching operation examples in model execution of BPMN; the method comprises the following steps: step 1: arranging parameters corresponding to the BPMN business process; step 2: receiving the input parameter value and initial visiting requirement used for initially visiting the BPMN business process, establishing an operation example for the BPMNbusiness process, and establishing a mapping relation item between the input parameter value used for initially visiting the BPMN business process and the established operation example in a mapping table; and step 3: receiving the input parameter value and the subsequent visiting request used for re-visiting a BPMN business process, and querying the operation example having mapping relationship with the input parameter value used for re-visiting the BPMN business process in the mapping table. The method avoids the situation that a plurality of operation examples may be generated due to execution of one BPMN business process many times in the prior art and ensures the matching of the operation examples in the execution process of the BPMN model.

Description

technical field [0001] The present invention relates to the field of service composition in computer technology, in particular to a method and system for matching running instances in the execution of a Business Process Modeling Notation (BPMN) model. Background technique [0002] The development of computer technology has experienced a development process from centralized to distributed, from single to diverse, from independent to mutual integration. However, computing and information silos still exist. In the current open, dynamic, and complex computing environment, it is difficult for traditional computing technologies to fully share computing power and information resources. Service-Oriented Computing (SOC) and Service-Oriented Architecture (Service-Oriented Architecture (SOA for short) has been widely accepted and has become the computing paradigm and architecture for constructing the next generation of distributed applications. SOA embodies the characteristics of the...

However, the problem with this method is that since BPMN has more information than BPEL, simple mapping will lead to a lack of information, and in terms of control flow patterns, BPMN's operational semantics are far richer than BPEL, and mapping will cause BPEL to fail to fully Represents the execution semantics of a BPMN model

[0008] The problem with the method of directly executing BPMN provided in the prior art is that it is impossible to guarantee the matching of running instances during BPMN execution

The so-called running instance is similar to the simultaneous instantiation of a class into multiple objects in an object-oriented program. The same BPMN business process can be instantiated into multiple concurrently executing running instances in the execution engine. Each running instance may Perform multiple message flow interactions with clients, web servers, or other running instances. For example, the same running instance is used twice during the execution of a BPMN model. According to the correct execution process, the second use The running instance should be the same as the running instance used for the first time, but because the same BPMN business process can be instantiated into multiple running instances, it is difficult to ensure that the second use The obtained running instance is the running instance used for the first time, which will lead to a mismatch of running instances, resulting in the failure of the BPMN model to be successfully executed
