以學名結構為基礎之UML資料模型和XML之轉換模式 / A Generic Construct based Transformation Model between UML Data Model and XML郭宛毓, Wan-Yu Kuo Unknown Date (has links)
XML (eXtensible Markup Language)已經快速成為網際網路上資料交換的標準,其架構適合用來描述複雜的資料結構並提供XML文件驗證的機制。要交換XML文件,就必須使用綱要語言來制定XML語彙,因而由此衍生出XML綱要設計之問題。在本篇研究中,將研究UML資料模型與XML綱要之間轉換的議題並發展一個可進行雙向轉換的模型。此轉換模型包含二部份,一是從UML資料模型結構轉換為XML綱要結構,一是從XML綱要結構反向轉換為UML資料模型結構;這二個模型將分別探討XML DTD (Data Type Definition)及 W3C XML Schema二個主題,將這二個子模型分別從語法及語意轉換之層面切入進行一連串結構轉換規則之延伸及建立。在XML綱要結構反向轉換為UML資料模型結構之模型中亦包含二個子模型,分別由XML綱要結構建立轉換之規則。我們建立此轉換模型之目的在於使UML資料模型結構及XML綱要結構間之轉換方法更為明確、簡單及容易使用,並透過系統實作來驗證其可行性。 / The (eXtensible Markup Language) XML is fast becoming the standard data exchange across the Internet. It is suitable to describe complex-structured data. It also provides a validation mechanism to validate vocabulary used in the XML document. In order to exchange XML document, XML vocabulary needs to be defined. As a result spread out the issues of XML schema design from here. In the research, UML data model and XML schema transformation issue have been studied to develop a bi-directional mapping and transformation model. We design the bidirectional mapping and transformation model in two parts. One is from UML data model to XML schema; another is from XML Schema to UML data model. Each part has two explored subject, including XML DTD (Data Type Definition) and W3C XML Schema. We develop a sequence of transformation rules from the viewpoints of syntactic and semantic transformation. These are also two parts in the transformation model of mapping from XML schema to UML data model. We develop transformation rules from the viewpoints of generic XML constructs step by step. We build up the transformation model to make transformation method more generic, genuine, systematic, explicit, simple and easy to use. Besides, we implement a transformation editor to validate the bi-directional transformation model.

股價指數漲跌規則之知識管理涂金櫻, ChinYin Tu Unknown Date (has links)
金融商品的價值是否可以預測呢?由避險基金的操作績效以及華爾街著名分析師的事前看法和事後印證來看,答案幾乎是肯定的。不過,大多數的投資人卻依然無法獲利。站在學術的角度上來看,[Fama ,1970]的效率市場假說告訴我們,一個有效率的市場是無法獲得超額報酬的,這論點也經常被學者用來檢驗市場是否具有效率性,研究的結果也都是證明市場是無效率的。因此,我們希望藉由發展專家對於股價指數的漲跌推論規則之本體論來提升金融商品領域之知識管理的廣度與深度。
本體論(Ontology)是知識管理的表現方式之一,[Gruber ,1993]闡述本體論是一種詞彙的規格,用來呈現我們想要分享的領域;可以定義類別、關係、功能、與其他物件。由於本體論提供的是一個領域嚴謹豐富的理論因此相當適合使用在知識工程的領域上[劉紅閣、鄭麗萍與張少方 ,2005]。另外,本體論的建構過程和物件導向設計非常的類似[Chandrasekaran, Josephson & Benjamins ,1999],因此,在研究的過程中,我們將以物件導向設計來輔助本體論的分析。最後,使用Protégé 3.0這套相當普及化的本體論編輯工具作為系統實做的工具。 / Is the value of Financial banking products predicable? In view of the operating performance of hedge fund and the preliminary insights and the evidences afterward from the well-known analyst of Wall Street, the answer is almost positive. Nevertheless, the majority of investors still can not make profits from it. Based on the Academic points, (Fama, 1970) the theory of hypothesis if efficient market showed us that we can not make extra profits from the efficient market. And it is often used to examine whether the market is of efficiency. And the result of research also proved that the market is inefficient. Therefore, it is desired that we enhance the width and deepness of knowledge management of financial banking products with the Ontology of the inferred up-and-down principal of stock index developed by the efforts of experts.
Ontology is one of the ways presenting knowledge management. (Gruber, 1993) explains that the ontology is the specifications of terminology which presents the domains we would like to share with. Classes, Relations, functions and other objects could be defined by that. Ontology provide us with the theory of strictness and richness of domains, therefore, it is very suitably utilized in the domains of knowledge engineering[劉紅閣、鄭麗萍與張少方 ,2005]. Besides, the construction process of Ontology is very similar to the object-oriented design. [Chandrasekaran, Josephson & Benjamins ,1999] Based on this, we will use the object-oriented design to assist the analysis of Ontology through our research . At last, Protégé 3.0 which is the very popular editing tool of Ontology is used as a tool for the system implementation.

模型驅動架構下工作流程模型之分析與設計楊國源, Yang,Kuo Yuan Unknown Date (has links)
本研究遵循模型驅動架構的概念,發展一適用於現實商業流程之工作流程模型,採用創新的方式對於工作流程做描述,我們只需要按照固定的步驟,便可以將真實的商業流程發展成可用的模型,以利於後續發展工作流程系統之用。在發展模型時,我們採用了IBM的資訊框架(IFW)做為塑模的方式,以及利用統一塑模語言中的狀態移轉圖和循序圖的概念來做為呈現工作流程模型,解決了傳統流程無法表達流程內部資料變化所帶來的影響,除此之外,我們在模型發展後,採用包含事件-驅動概念的工作流程引擎來產生工作流程系統,我們將商業流程視為一個個的物件,物件收發事件導致狀態的改變而引發另一個事件的發生,如此循環下去,直到整個流程完成。

具整合性與互通性會計與決策管理系統之資訊模式建立--以某全球化營運之高科技公司個案研究 / An Integral and Interoperable Information Model Design of Accounting and Decision Management System--A Global High-Tech Corp Case Study石太基, Shih, Tai-chi Unknown Date (has links)
傳統會計與決策管理系統受限於現行財務會計報導的架構,並未儲存與財務無關,或不能以金額衡量的資訊,無法對非財務性決策提供有效的幫助。而資訊語意的差異更使得傳統會計與決策管理系統不易與企業內其他資訊系統互通,造成系統整合上的困擾,歷來不斷有學者探討會計與決策管理系統資訊模式建立之方法,以增進會計與決策管理系統資訊模式的有用性。
本研究提出會計與決策管理系統資訊模式建立之框架與方法,強調會計與決策管理系統之建構,應與企業策略發展整體考量,同時導入REA model整合企業整體資訊模式與財會專業資訊模式,並採用UML作為系統發展流程之塑模工具,編製系統發展有關文件,以利後續選擇解決方案的映對程序,確認解決方案符合使用者需求,及增進會計與決策管理系統在企業內的整合性與互通性。 / Traditional accounting and decision management information system cannot support non-financial decision making, because there is only stored financial information without non-financial information due to the current financial accounting reporting structure. The information semantic differences block interoperability between accounting and decision management information system within the organization. And it also has caused the challenge of enterprise information integration. Researchers strive to find viable information modeling process or method to help accounting and decision management information system to be constructed.
This thesis presents accounting and decision management information system information modeling framework and process. The framework stresses the construction of accounting and decision management information system must connect with enterprise vision and strategy. It also adopts and expands REA model to integrate accounting information model and enterprise information model at information modeling process. UML is a high-level modeling tool to develop system processes. The goal is to provide a standard method to develop system blueprints beyond tool-specific system solutions and to apply UML modeling documents to map different system solutions and make sure the solution fit with user requirements, and improve the integration and interoperability for accounting and decision management information system design and development.
