Distributed and concurrent processing of business object documentsin support of e-enterprise integration

摘要

The Internet and distributed object technologies have made itpossible for different business enterprises to draw upon the best oftheir resources for conducting joint business as a virtual e-enterprise(VEE). To enable virtual e-enterprises, the integration of legacyapplications and the modeling and enactment of concurrent businessprocesses are necessary. The authors combine the features of themessaging approach and the distributed object approach to systemintegration. Business Object Documents (BOD) are used for transmittingbusiness operations and data among application systems. Messagetransmission is supported by two underlying communicationinfrastructures: CORBA and Java RMI. The separation of messaging fromcommunication infrastructure allows the underlying infrastructure to bechanged without impacting application systems. Also, business processesare modeled as sequences or network structures of BOD transmissions. Theprocess models are replicated at all sites and used by an extendedinformation infrastructure to enable distributed, concurrent enactmentof processes
