| 摘 要： | 福建前兆台网系统已经运行2年多，期间出现一些数据交换与同步问题，严重影响数据上传的效率。通过简要介绍数据交换与同步的原理，结合同步数据内容所产生的问题进行分析并形成一套解决方法。实践结果表明，维护好QZDATA表空间、应用服务器和管理系统并掌握一定数据库程序设计基础就能够基本满足区域前兆数据库维护工作，保证数据上传的效率。

| Abstract: | There is exchange and synchronization problems existed in precursor network in Fujian which influenced uploading efficiency. In this paper, a brief introduction to data exchange and syn- chronization principle combined with the problems arising from data synchronization, finally, the au- thors analyze the problems and form a set of solutions. The practical results show that the better ma- intenance of the data table space and application server and management system and also mastering some database programming foundation will be able to basically meet the regional precursor database maintenance so that to ensure the efficiency of data upload. |
