面向文档审批的可视化工作流系统设计

Design of Visual Workflow System for Approving of Object-Oriented Documents

面向文档审批的可视化工作流系统由审批流建模、引擎和监视器,及客户端程序、后台应用等组成。审批流建模把需要计算机审批的业务流程转化为计算机可识别逻辑模型。在Delphi开发环境采用基于ExpressFlowChart控件的面向对象技术实现可视化建模。审批动引擎为审批流实例提供给运行环境软件服务器,用数据库扫描实现对流程的控制。

The visual workflow system based on approving of object-oriented document is composed of workflow modeling, workflow engine and monitor, client and background application. Approving workflow modeling is that operation process approved by computer can be converted to logical model that computer can identify. Visual workflow modeling is realized by using OO technique and ExpressFlowChart controller in Delphi development environment. Approving workflow engine used as approving workflow example was provided to software server in running environment, and workflow engine can control flow process scanned by database.
