A process-oriented composite application aggregates functionality from a number of other applications and coordinates these applications according to a process model. Traditional approaches to develop process-oriented composite application rely on statically defined process models that are deployed into a process management engine. This approach has the advantage that application designers and users can comprehend the dependencies between the applications involved in the composition by referring to the process model. A major disadvantage however is that once deployed the behaviour of every execution of the composite application is expected to abide by its process model until this model is changed and re-deployed. This makes it difficult to enrich the application with even minor features, to plug-in new applications into the composition, or to hot-fix the composite application to meet special circumstances or demands (e.g. to personalise the application). This paper describes a technique for translating a process-oriented application into an event-based application which is more amenable to such runtime adaptation. The process-based and event-based views of the application can then co-exist and be synchronised offline if the changes become permanent and it is found desirable to reflect them in the process model.
Impact and interest:
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
