摘要
阐述了气象信息管理系统中资料归档的设计及实现,并根据资料归档对数据备份速率以及数据管理的需求,将oracle10g中新引进的数据泵技术应用在数据导出中,较好地解决了由原备份工具EXP带来的归档速率不高等问题。从而提高了系统运行的效率,并且使系统的实用性得到了提高。
The paper describes the design and implementation of data arehiving in the meteorological information management system, and in accordance with the needs of data archiving for data backup and data management, the new data pump technology applications introduced in oracle10g is derived, which is a better solution to the problems of archiving with low velocity which is caused by EXP and thereby improves the efficiency of the system running and the utility of the system.
