摘 要
工作流就是一系列相互銜接、自動進行的業務活動或任務。工作流引擎是工作流管理系統的核心,它的主要功能是通過計算機技術的支持去定義、執行和管理工作流,協調工作流執行過程中工作之間以及群體成員之間的信息交互。
論文主要講述了工作流引擎的基本功能及設計方法,介紹工作流引擎的基本原理,具體分析了工作流引擎所包含的內容,詳細介紹了相關的信息模型和控制模型。系統采用關系結構的理念來設計工作流引擎,給出了用Microsoft Visual Studio 2005和Microsoft SQL Server2000實現系統的方法。論文中利用本工作流引擎構建系統能適應大多數業務流程的扭轉,大大縮短常見信息系統的項目開發周期,提高效率。

Abstract
Workflow is a series of interlocking, automatic business activities or tasks. Workflow engine is the work flow management system in the core, and its main function is to define, implement and manage work flow through the support of computer technology as well as co-ordinate work flow process of working implementation and groups of information between members of interaction.
The thesis has mainly described basic functions and design of the workflow engine, introduced the basic theories, and specifically analyzed the content included in the work flow and the details of the relevant information model and control model. The idea of relation structure has been used to design this system and the method to achieve the system function with Microsoft Visual Studio 2005 and Microsoft SQL Server2000 has been given out. Constructing system with the workflow engine can adapt to the majority of the business process reversing that significantly reduce the development cycle of the common information system and improve efficiency.
