The Design And Implementation Of Cloud Workflow Template Defining Tool

The emergence of workflow product makes the paperless office possible. As the rapid development of economy, the initial workflow management system couldn’t meet the requirement of the enterprise’s development, for which is lack of the data storage and the low computational efficiency. Most enterprises don’t have superior resources and services because of the funds shortage. Cloud computing is a computational mode which is flexible, customizable, and paid-on-demand. It offers all kinds of basic resources and services that have high performance. In this case, the cloud workflow management system comes into existence, of which one of the basic parts is the cloud workflow template defining tool. This thesis is mainly about the design and implementation of the cloud workflow template defining tool. For above all, there are three aspects to discuss.First, the basic theories of workflow management technique, the future development of workflow management system and recent development of cloud workflow-based management system are discussed. The cloud computing architecture is analyzed. In this part, MapReduce work flow and some typical cloud computing services are introduced. And then, the thesis gives a thorough analysis to the workflow reference model and element model of XPDL language.Second, according to the research and analysis, the design of the cloud workflow template defining tool is discussed, including the design of architecture and some details.Third, the implementation of the template defining tool is discussed. According to the detailed design, the work of a variety of classes and interface is completed. In the end, the template is showed in an instance.
