基于XML的Web异种数据库操作模型的研究

互连网的迅速发展使得Web数据库成为数据库应用的主流,随着网上数据量的增加,越来越多的应用迫切需要通过网络来交换数据。然而,目前的Web数据库实现技术与数据库在设计结构和平台上的差异给数据库的网络操作带来了实现上的困难,同时数据库操作的网络开放会带来诸多安全隐患。基于此,该文提出了一种基于XML的Web异种数据库操作模型,设计了请求和结果XML文档的一般结构(DTD),讨论了该模型在确保数据库安全的条件下,完成异种数据库在Web上的数据交换和共享的工作过程。

Research on Operation of Heterogeneous Web-Databases-Model Based on XML

The rapid development of Internet makes the Web database become the main application of database system.Along with the burst of increase of Web data,there are more and more applied requirements for exchanging data through network.However,today's practical technology and heterogeneity of Web databases become the obstacle of realizing the operation of heterogeneous databases,meanwhile,the operation through network will cause security problem.This paper proposes an interoperation model for Web heterogeneous databases,designs the Document Type Definition for request and answer XML document and discusses the process of exchanging or sharing data between heterogeneous Web databases under the guarantee of security using this model.
