Abstract


Enterprise Application Integration EAI enterprise legacy and new information systems integration , workflow management is one of the key technologies to integrate these systems . Workflow management technology in enterprise application integration EAI will be a different system organizations coordinate the formation of collaborative workflow . Flexible changing needs of the current heterogeneous workflow management technology can not adapt to business systems and processes , and the lack of support for cross-enterprise EAI . SOA architecture as a support distributed computing model of the system loosely coupled heterogeneous environments , with low implementation cost , and good interface openness characteristics . Thesis SOA architecture EAI workflow management to study the integration of heterogeneous systems , business processes demand change and cross- enterprise application integration . The paper is mainly carried out the following work : 1 . Heterogeneous business systems in the EAI and workflow platform interface . Use of the service packaging technology heterogeneous business systems through a unified service interface open , hidden differences in system development technology, operating environment , and reducing the system interface consideration . UDDI service registry to achieve unified management within the enterprise and outside the enterprise services , which provide support for cross-enterprise workflow run . Changes in demand for EAI workflow flexibility , SOA-based dynamic workflow technology . A support workflow flexibility to change the activities to be able to dynamically select services based on functional and QoS requirements , and map the workflow based on the the dynamic BPEL workflow description and enforcement mechanisms and a service selection and combination algorithm QSSCA , activities , but also according to the input and output parameters and functions defined certain services automatically combined and mapped to a more complex service workflow . 3 on the basis of the above research work , the paper presents a workflow management system for building the EAI application model based on SOA, workflow management model SWMM . Actual application demand , combined with a logistics enterprises , SWMM - based the experiment prototype system development , focusing on validated model of the service package , the process is flexible, and the feasibility and effectiveness of the service function of the dynamic combination of options and services .
