【摘要】：隨著信息技術(shù)的飛速發(fā)展,信息化產(chǎn)業(yè)不斷地升級(jí),企業(yè)信息化進(jìn)程的加快,企業(yè)或者個(gè)人之間越來越需要溝通。為了提高企業(yè)的綜合競(jìng)爭(zhēng)力,企業(yè)往往會(huì)根據(jù)自身的規(guī)模采用多種應(yīng)用軟件系統(tǒng)來支撐其業(yè)務(wù)發(fā)展,由于系統(tǒng)之間相互獨(dú)立,缺乏數(shù)據(jù)的通信和共享,由此形成的“信息孤島”大量存在。研究如何對(duì)這些異構(gòu)系統(tǒng)的異構(gòu)數(shù)據(jù)實(shí)現(xiàn)有效集成,構(gòu)建統(tǒng)一的異構(gòu)數(shù)據(jù)集成平臺(tái),實(shí)現(xiàn)企業(yè)數(shù)據(jù)的交流和共享成為企業(yè)應(yīng)用的重要研究目標(biāo)。隨著XML、Web服務(wù)、Web語義技術(shù)、本體論等技術(shù)的在數(shù)據(jù)集成領(lǐng)域廣泛應(yīng)用,憑借SOA的諸多優(yōu)勢(shì),將SOA應(yīng)用于企業(yè)異構(gòu)數(shù)據(jù)集成也越來越受到人們的關(guān)注。 目前國(guó)內(nèi)外專家已經(jīng)提出了一些異構(gòu)數(shù)據(jù)集成的技術(shù),但他們?cè)跐M足用戶訪問需求方面還存在很多不足。為了解決上述問題,本文在對(duì)現(xiàn)有的異構(gòu)數(shù)據(jù)集成理論和異構(gòu)數(shù)據(jù)集成方法進(jìn)行研究的基礎(chǔ)上,利用SOA設(shè)計(jì)思想,采用Web服務(wù)等相關(guān)技術(shù),提出了一種基于SOA的企業(yè)異構(gòu)數(shù)據(jù)集成系統(tǒng)框架。 論文分析了當(dāng)前常用的一些異構(gòu)數(shù)據(jù)集成方法,并比較了這些方法的優(yōu)缺點(diǎn),針對(duì)現(xiàn)有異構(gòu)數(shù)據(jù)集成方法存在的不足之處,探討了在SOA上進(jìn)行企業(yè)異構(gòu)數(shù)據(jù)集成的可行性,利用XML、Web服務(wù)等技術(shù)對(duì)SOA的支持,設(shè)計(jì)了一個(gè)基于SOA的企業(yè)異構(gòu)數(shù)據(jù)集成系統(tǒng)框架。該框架分為服務(wù)提供層和服務(wù)接口層兩層結(jié)構(gòu),服務(wù)提供層包含數(shù)據(jù)源適配器、數(shù)據(jù)引擎、數(shù)據(jù)服務(wù)、注冊(cè)管理、安全管理等模塊,主要負(fù)責(zé)與數(shù)據(jù)庫交互,對(duì)數(shù)據(jù)庫中的數(shù)據(jù)進(jìn)行處理,為服務(wù)接口層提供數(shù)據(jù)服務(wù),并對(duì)數(shù)據(jù)庫、用戶安全登錄等進(jìn)行管理；服務(wù)接口層主要包含服務(wù)解析和服務(wù)管理兩個(gè)模塊,負(fù)責(zé)對(duì)數(shù)據(jù)的服務(wù)封裝及服務(wù)的查找、調(diào)用、組合等處理。本系統(tǒng)的優(yōu)勢(shì)在于引入了Web服務(wù),采用SOA的思想,以服務(wù)為核心,把系統(tǒng)的數(shù)據(jù)刪除、查找、更新等功能都封裝為服務(wù),屏蔽了用戶與數(shù)據(jù)之間的具體交互過程,實(shí)現(xiàn)了用戶對(duì)異構(gòu)數(shù)據(jù)的透明訪問。最后論文以某軟件公司為背景對(duì)本文提出的系統(tǒng)框架進(jìn)行了應(yīng)用分析與設(shè)計(jì),證明了該系統(tǒng)的實(shí)用性,并通過實(shí)驗(yàn),設(shè)計(jì)了一個(gè)異構(gòu)數(shù)據(jù)集成系統(tǒng),進(jìn)一步驗(yàn)證了本文研究工作的正確性和有效性。
[Abstract]:With the rapid development of information technology, the continuous upgrading of information industry, the acceleration of enterprise informatization process, enterprises or individuals more and more need to communicate. In order to improve the comprehensive competitiveness of enterprises, enterprises often adopt a variety of application software systems to support their business development according to their own scale. Because the systems are independent of each other, there is a lack of data communication and sharing. The resulting "information island" exists in large numbers. How to effectively integrate the heterogeneous data of these heterogeneous systems, construct a unified heterogeneous data integration platform, and realize the exchange and sharing of enterprise data has become an important research goal of enterprise application. With the wide application of XML,Web services, Web semantic technology, ontology and other technologies in the field of data integration, the application of SOA to heterogeneous data integration in enterprises has attracted more and more attention with the help of many advantages of SOA. At present, experts at home and abroad have put forward some heterogeneous data integration technologies, but they still have a lot of shortcomings in meeting user access requirements. In order to solve the above problems, based on the research of the existing heterogeneous data integration theory and heterogeneous data integration methods, this paper uses SOA design ideas and Web services and other related technologies. A framework of heterogeneous data integration system based on SOA is proposed. This paper analyzes some current heterogeneous data integration methods, compares their advantages and disadvantages, and discusses the feasibility of enterprise heterogeneous data integration based on SOA, aiming at the shortcomings of existing heterogeneous data integration methods. A framework of enterprise heterogeneous data integration system based on SOA is designed by using XML,Web services and other technologies to support SOA. The framework is divided into two layers: service provider layer and service interface layer, which includes data source adapter, data engine, data service, registration management, security management and so on. The data in the database is processed to provide the data service for the service interface layer, and to manage the database, user safe login, etc. The service interface layer mainly includes two modules: service resolution and service management. Responsible for data encapsulation and service search, call, composition, etc. The advantage of this system lies in introducing the Web service, adopting the idea of SOA, taking the service as the core, encapsulating the data deletion, searching, updating and other functions of the system as the service, shielding the concrete interactive process between the user and the data. The user can access the heterogeneous data transparently. Finally, based on the background of a software company, the application analysis and design of the proposed system framework are carried out, and the practicability of the system is proved. Through experiments, a heterogeneous data integration system is designed. The correctness and validity of the research work are further verified.
