Research And Implementation Of Web Customed Workflow Model For Approval Business

With the emergence of Web2.0 technology and the continuous development of enterprises,workflow technology in the production and living needs of the place growing.In the past,the workflow technology has paid less attention to the demand of user-defined workflow templates in the small and medium-sized enterprise approval business.Based on the combination of its own characteristics and the summary of the approval process mode,we propose a web customed workflow model.The core is to implement a lightweight workflow engine that satisfies the user's Web page-side custom workflow template needs and checks the user-defined workflow template to ensure that it can be executed properly in the engine.First of all,the history of the development of workflow and the status quo of research at home and abroad were discussed,combined with the characteristics of small and medium-sized enterprises that small and medium-sized enterprise approval business for Web custom workflow has an urgent need for the concept of workflow related interpretation.Workflow management system and the current technology architecture used in the development of the technology were summarized.Secondly,with the Qinhuangdao yogma travel approval business needs for the typical small and medium enterprises to review and approve business analysis of the four approval process mode,followed by a simplified version of the map based on the custom workflow template technology to achieve Web page custom workflow,And design element types to develop custom workflow rules.In order to ensure that the user-defined workflow template can be used normally,the integrity check and die wait algorithm and multi-instance verification algorithm of the workflow template are designed and implemented.On this basis,the core of the workflow model is designed,Lightweight workflow engine,designed and implemented the engine execution algorithm and node task routing allocation strategy.Finally,the implementation of the web customed workflow model is described in detail.The content includes the five-layer technology architecture of the model,the design of the workflow model database and the implementation effect of the web page-side customed workflow template.The paper introduces the definition of the custom template Integrity checking algorithm,dead wait and multi-instance checking algorithm,workflow engine execution algorithm and node task routing algorithm.
