Abstract

中文摘要 在未來的網路雲端運算環境中，將充滿著各式各樣的分散式網路服務與大量資料，而 雲端運算的應用層通常以服務導向架構的方式提供給服務需求者使用，大量資料則藏在網 路服務(Web Services)的背後，如何能幫助企業或使用者在服務導向雲端運算環境中動態且 即時的挖掘出所需資料的組合，做為決策或預測的判斷，將是重要的研究議題。因此在本 研究計畫中，將建立關聯網路服務資料驅動引擎，透過動態工作流程的方法建構服務導向 雲端運算環境中的即時動態資料驅動架構，找出動態雲端資料流，解決在雲端運算環境中 大量資料分散、串連不易、與無法動態分析資料需求的問題，結果將可做為決策或預測的 參考。 本計畫提出整合網路服務技術與動態資料驅動應用系統模型的研究，導入雲端運算環 境中，搭配推薦系統、語意網、知識庫、動態工作流程、網路服務組合等方法，完成基於 雲端運算的服務導向動態資料驅動應用系統的架構。研究內容主要包括：第一年：建構服 務導向雲端運算環境中的資料驅動引擎。第二年：建構服務導向雲端運算環境中的動態資 料驅動基本元件，找出靜態雲端資料流。第三年：建構服務導向雲端運算環境中的動態資 料驅動架構， 找出動態雲端資料流。在架構中也將導入WS-Security 標準與 RBAC(Role-based Access Control)的機制，建立服務導向雲端運算動態資料驅動架構中安全 的資料傳輸環境。本計畫將發展與實作出此方法架構與系統，實際在一個有即時資料變動 的領域測試實用，並進行方法的評估。

Abstract It will be full of distributed network services and a large quantity of data in the future cloud computing network environment. The application layer of cloud computing usually provides services to the service consumers based on the service-oriented architecture. Behind the network services, there is a large amount of data. So how to assist enterprises or individuals to mine the combination of usable data dynamically hidden behind the network services in service-oriented cloud computing environment in order to make decisions and predictions will be an important issue. Therefore, in this research we will figure out the problem that with a large amount of data distribution, rough connections, and are unable to do data analysis dynamically. We establish relational web services data-driven engine, and build the real-time dynamic data driven application system architecture based on service-oriented cloud computing environment with dynamical workflow approach. Then we find out the dynamical cloud data flow to be the references of decision and prediction making. This research provides the integration of web service techniques and dynamical data driven application system module. We implement cloud computing environment with recommendation systems, semantic web, knowledge base, dynamic workflow, and web service composition to accomplish service-oriented dynamic data driven architecture based on cloud computing. The major contents of this research are as followed: in the first year, we build data-driven engine under service-oriented cloud computing environment. In the second year, we establish the basic elements of dynamic data driven application system under service-oriented cloud computing environment and to find out static cloud data flow. In the third year, we establish service-oriented dynamic data driven application system architecture based on cloud computing and to find out dynamic cloud data flow. In this research, we also use WS-Security standard and RBAC (Role-base Access Control) mechanism to establish a secure data transmission environment in proposed service-oriented dynamic data driven application system architecture based on cloud computing. We develop the approach and implement the system for individuals or enterprises to find out dynamic cloud data flow, test this approach in a domain with real-time data alteration, and then evaluate this approach.
