ServicesXWVDL(XML-based Workflow View Definition Language)is a language for workflow views definition,which is expanded from XPDL.Workflow View Design Tool is a GUI editor for workflow view design based on existing workflow definitions.View Manager controls the load and unload of view definitions,and also administrates view instances.System administrators can control the View Manager via View Administration Tool.Monitoring Controller maintains the consistence between workflow view instances and underlying workflow instances.Users can monitor the progress of business processes via View Client Application.The updating on workflow views may be ambiguous,just like the updating on database views.We have proposed a deputy model to resolve this problem,which is embedded in Updating Mechanism.Workflow View is a sound interface of enterprise systems for advanced B2B collaborations.Based on the workflow view engine,B2B interface controls the interactions with the systems of other enterprises via web services,such as BPEL4WS and ebXML BPSS.本人已有的相关工作MDB,Workflow,Web
