摘 要
工作流就是一系列相互銜接、自動(dòng)進(jìn)行的業(yè)務(wù)活動(dòng)或任務(wù)。工作流引擎是工作流管理系統(tǒng)的核心，它的主要功能是通過計(jì)算機(jī)技術(shù)的支持去定義、執(zhí)行和管理工作流，協(xié)調(diào)工作流執(zhí)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(shè)計(jì)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(nèi)容，詳細(xì)介紹了相關(guān)的信息模型和控制模型。系統(tǒng)采用關(guān)系結(jié)構(gòu)的理念來設(shè)計(jì)工作流引擎，給出了用Microsoft Visual Studio 2005和Microsoft SQL Server2000實(shí)現(xiàn)系統(tǒng)的方法。論文中利用本工作流引擎構(gòu)建系統(tǒng)能適應(yīng)大多數(shù)業(yè)務(wù)流程的扭轉(zhuǎn)，大大縮短常見信息系統(tǒng)的項(xiàng)目開發(fā)周期，提高效率。

The design of information system frame based on workflow engine
---- The subsystem of workflow engine
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.
Key words： Workflow engine; Critical business; Relationship
