the key point that exploits xml to establish the isomerous database integration model, is to set up the conversion relationship between xml and database.
利用xml技术建立异构数据库集成模型的关键是建立xml与数据库之间的转换关系。
with xml as the common model, the uniform conversion instrument of isomerous database is set up through the reversible bidirectional conversion between relational database and xml.
以xml为公共模型,通过关系数据库与xml的可逆双向转换,建立异构关系数据源的统一转换工具。
the intrusion tolerance database based on redundancy is made of several isomerous database servers. and by adding redundancy cell, it achieves the survival and availability of database.
基于冗余的入侵容忍数据库是由多个异构数据库服务器组成的,通过增加冗余单元实现数据库的可生存性和可用性,但是冗余会引起系统性能下降。
this paper summarizes the design principle and technology on information integration of isomerous database in sb cims , offers a brief introduction to its function and algorithm.
本文分析阐述了sb-cims异构数据库信息集成的设计原理与实现技术,并对其功能特点及算法作了概要介绍。
