摘要
针对基于Web的工作流管理系统中表单建模存在的数据结构不合理、维护困难、效率低、缺乏数据柔性和结构柔性等问题,分析了表单数据特点及传统表单建模方法的缺陷,提出一种基于XML和关系数据库的表单柔性建模方法,给出基于表单的流程推动模型及实现方法,引入了数据集控件和自定义函数控件,增强了系统的可扩展性和柔性,满足了工作流管理系统中对表单定义处理灵活性的要求。
Aimed for the problems of unreasonable data structure, difficult maintenance, inefficient and shortage of data flexibility and structure flexibility in form modeling of workflow management system based on web, the data characteristic of form and the defect of traditional form modeling method is analyzed, and a flexible modeling method of form based on XML and RDBMS is devised. A process promotion model based on form and its implementation are presented. Imported the dataset component and the custom function component, the scalability and flexibility are enhanced and the requirements to flexibility of form defmition processing in workflow management system are satisfied.
