淺析OA流程的可視化方法

1、關(guān)鍵詞：關(guān)鍵詞：工作流；流程定義；可視化；JavaApplet淺析OA流程的可視化方法摘要工作流是指整個(gè)或部分業(yè)務(wù)流程在計(jì)算機(jī)支持下的全自動(dòng)或半自動(dòng)化。在計(jì)算機(jī)網(wǎng)絡(luò)環(huán)境下，工作任務(wù)在多個(gè)人或單位之間的流轉(zhuǎn)實(shí)際上將表現(xiàn)為信息或數(shù)據(jù)在多個(gè)人之間的傳送。使用可視化的0A工作流設(shè)計(jì)工具，用戶不需要編程就可以定義設(shè)計(jì)出滿足要求的收發(fā)文流程，實(shí)際使用效果良好。論文以可視化的0A工作流設(shè)計(jì)工具的開發(fā)為基礎(chǔ)，主要闡述五個(gè)方面的內(nèi)容。第一部分介紹了工作流和工作流設(shè)計(jì)工具的相關(guān)概念與開發(fā)背景；第二部分對(duì)工作相關(guān)基礎(chǔ)理論技術(shù)、系統(tǒng)環(huán)境與平臺(tái)基礎(chǔ)、以及開發(fā)技術(shù)進(jìn)行了描述；第三部分對(duì)系統(tǒng)功能進(jìn)行了分析；第四部分詳細(xì)介紹

2、了系統(tǒng)流程、流程可視化設(shè)計(jì)的實(shí)際開發(fā)過程中使用到的關(guān)鍵技術(shù)；最后一部分在總結(jié)了系統(tǒng)開發(fā)心得的同時(shí)，提出了目前系統(tǒng)存在的不足和有待改進(jìn)的地方。591論文網(wǎng)591論文網(wǎng)www.591LW.com論文網(wǎng)TheResearchandImplementationofVisualOAworkflowBasedonB/SStructureAbstractWorkflowisafullautomationorsemi-automationonbusinessprocess,whichissupportedbythecomputertechnology.Inthedistributedenvironment,t
