臺灣博碩士論文加值系統

近年來由於資訊科技以及網際網路的發展，不論是個人、政府或是企業，資訊化的程度均逐年增加，因此資料交換的也需求日漸增加，且資料交換量亦不可同日而語。為了滿足在各種不同的系統之間完成資料交換的動作，本論文提出了一個以REST(Representational State Transfer)概念設計且以XML(eXtensible Markup Language)作為資料載體的以RESTful風格為基礎之開放式交換系統(RESTful Design Open Electronic Data Interchange,ROpenEDI)。我們以WebAPI的方式提供資料交換的服務，異質系統可以透過WebAPI進行資料索取的請求。
所提出的ROpenEDI的架構擁有三個角色分別是：資料提供者(Data Provider)、資料消費者(Data Consumer)以及ROpenEDI。資料提供者為加入ROpenEDI的系統，必頇提供一個API供ROpenEDI讀取資料；資料消費者則為索取資料方，可透過ROpenEDI獲得需要的資料，且資料已經由ROpenEDI轉換完成；ROpenEDI為本論文的主體，主要工作為聯繫資料提供者以及資料消費者，並且進行兩者之間資料格式的轉換。
在本研究中，我們以一個旅遊平台作為電子資料交換的例子。在例子中，各旅遊平台透過資料交換系統提供的API界面，進行旅遊景點以及行程相關資料的交換。透過ROpenEDI旅遊平台可以輕鬆的取得其他平台的資料，由於ROpenEDI可以自動在不同平台中轉換格式，因此旅遊平台只需要能解析他們在ROpenEDI中設定的格式即可，不需要了解每個平台的格式為何。因此可以降低各旅遊平台在解析資料時的負擔，此外旅遊平台也不需要擔心當有其他平台加入資料交換服務時，可能會遭遇到資料無法解析的問題。

Due to the rapid development of Internet and WWW, the degree of information technology of individuals, governments, or enterprises grow up year by year. The information exchange requirements of companies increase every day, and the amount of exchange data in today cannot be compared with what it was few years ago. In order to satisfy a variety of data exchange among systems, this paper addresses an RESTful Design Open Electronic Data Interchange system (ROpenEDI) based on the Representational State Transfer (REST) concept, and applies XML formats to the system data. We define several server-side Web APIs to provide data exchange services, so that heterogeneous systems can obtain on-demand data through our Web APIs.
The proposed ROpenEDI architecture includes three participants, Data Provider, Data Consumer, and ROpenEDI. Data Provider must provide an API to join the ROpenEDI, so that ROpenEDI can read data from Data Provider. Data Consumer as a consumption party can obtain data from Data Provider through ROpenEDI after the data format required by Consumer is transferred. ROpenEDI is the core of the system, whose major works are to contact with, and to transfer format between Data Provider and Data Consumer.
In this thesis, We present also a prototype of ROpenEDI, denoted as a tourism platform. The platform exchanges the tour spot and travel path information data via the ROpenEDI API interfaces, and easily extracts the required data from other external platforms through the core of ROpenEDI. ROpenEDI can automatically convert data format from different platforms, so that the tour platform only needs to parse data formats set on the core of ROpenEDI, and does not know the individual format in each of external platforms. Therefore, the proposed mechanism reduces the parsing overheads in the tourism platform. In addition, we donot worry about the problems of electronic data exchange, while other external platforms join the tour platform.
