摘　　要：在分析关系数据库中MARC数据存储特点的基础上,给出一种MARC数据镜像系统的设计方案。该方案通过引入文件传输服务器使得源数据库和目的数据库在进行数据复制时把远程操作转化成本地操作,把记录同步转化成网络文件传输,使得源数据库和目的数据库之间的数据复制可靠、快速而且有效。On the basis of analyzing the characteristic of the MARC data stored in the relation database, this paper proposes a kind of designing scheme of a MARC data mirror system. When the destination database replicats the MARC data from the source database, by introducing the file transfer server, this scheme transforms the remote operation to the local operation, changes the record synchronization into the network file transfer, and makes the replication of the MARC data between source and destination be more reliable, more effective and more applicable.
