摘要
传统异构数据库间的数据转换工具存在受平台限制、容易产生冗余等不足。可扩展标记语言(XML)提供了描述不同类型数据的标准格式,它建构在Unicode(统一码)之上,提供了对多语种的支持。本文以防汛调度领域为例,提出了一种基于XML元数据描述的领域异构数据库间数据转换的模型。
Traditional data transformation tools are constrained by the platform and easily lead to data redundancy.However,eXtensible Markup Language(XML) provides the standard format describing data in various types.XML builds on Unicode,so it supports many languages and has the virtue of globality.This paper puts forward a data transformation model described by XML metadata between heterogeneous databases in the flood prevention scheduling field.
