摘要
工作流技术在企业级管理软件中应用越来越广泛,工作流在运行过程中状态不断变化,及时了解工作流程的运行情况对用户来说至关重要,它既可以为用户采取的下一步处理提供依据,也可以让用户清楚了解该工作的处理情况,让用户做到"心中有数"。向用户展示工作流运行状态可以采用历史记录、流程图示等方式,而图示的方式更加形象、直观。以开源工作流为例,在研究典型的开源工作源图示模型的基础上,结合软件分层、设计模式等先进的软件设计理念提出一种通用的图示模型,有效减轻了表现层代码量,使得程序结构更加规范、合理与清晰,功能更加完善,提高了软件的健壮性、安全性、可维护性和可移植性,并在应用中取得了较好的效果。
Workflow technology applies to the enterprise management softwares more and more widely. The status of a running workflow is always changing, so it is very important for users to keep abreast of the running condition of the workflow, which can not only provide a basis for users to take the next step, but also provide them a clear understanding of the workflow situation. Historical record method, process graph method, etc., can be used to present the states of a running workflow to users, within which process graph method can directly display the information. In the research work an improved graph presentation model was proposed combined with advanced software design theorys such as layered software theory and design pattern, based on the research of open-source workflow. This improved model has reduced the code volume of the presentation layer effectively, has made the structure of the programme more standardized, reasonable and clearer, and the function more perfect, has improved the robustness, security, maintainability and portability of the software, and has made good results in the application.
