【摘要】 XML近来已成为科学与业务应用中数据表示的标准以及Web上应用间数据交换的标准。可以认为，对数据库研究人员来说，有关XML的研究是最有前途和挑战性的研究方向。然而，必须看到即使在全新的基于Web的应用中，由于关系数据库能提供有效、完善及用户熟悉并享于使用的功能服务设施，大量的数据已经并将继续在关系数据库中存储和管理。这就产生了基于关系数据库系统的、以XML格式交换业务数据的需求。在需求和技术的驱动下，如何解决基于关系数据库的XML存储和出版是近年来研究人员比较关注的一个课题。本文就此课题进行研究。 在这篇论文中，我们首先介绍XML相关技术及其与关系数据库的异构性；接着就学术界在基于关系数据库的XML存储和出版方面的学术成果进行了研究；然后我们就工业界三大数据库厂商各自的DBMS(Oracle、DB2、SQL Server)针对XML数据交换方面所做的功能扩展做了探讨；接着我们利用商业DBMS提供的扩展开发了数据交换技术在电子商务中的应用：网上书店零售商系统以及供应商系统；最后，我们进行了总结和展望。更多还原

【Abstract】 XML has recently established itself as the standard for representing data in scientific and business applications and the standard for exchanging data among applications on the Web. We therefore regard XML-related research as the most promising and challenging direction for the community of database researchers. But, it is noticed that most business data, even for new web-based applications, have and will be stored in relational databases, because relational databases can offer effective, perfect and user-familiar functions. This has created the requirement of exchanging business data in XML among applications based on relational database systems. Under the drive of requirement and technology, how to resolve the question of storing XML data by using an RDB and publishing relational data as an XML document is a hotspot. This paper addresses these issues.In this paper, we firstly present an introduction to XML-related technology and heterogeneity between XML and relational databases. Then we focus on the techniques of storing and publishing XML based on an RDB in academe. Next we introduce and review XML support for data exchange in commercial DBMSs( Oracle, DB2, SQL Server), which comes from industrial community. Then we have developed anapplication with commercial DBMSs in eBusiness domain--online bookstoreretailer’s system and supplier’s system. Finally, we conclude and forecast the perspectives of this domain.更多还原
