摘要
从现存分析预报体系数据库现状分析入手,指出了其存在的最大问题是资源未能得到充分共享和发挥最大功效,同时阐明数据仓库的面向主题、可重复使用、数据挖掘、高效的萃取功能及层次体系结构等优越性正好弥补了现存地震分析预报体系的不足,并根据地震系统的具体情况对数据仓库地震综合预报系统作初步设计,简要介绍了数据仓库地震综合预报系统的基本模型,最后对其应用前景作了展望。
Analyzing status quo of database of existent analysis and prediction system, the article shows that the existent biggest problem is that resource is not shared completely and exerted fully, and indicates the advantage of facing subject, reusability, data digging , efficient extraction function and hiberarchy of data storage makes up for deficiency of existent earthquake analysis and prediction system. According to detailed conditions of earthquake system, the author designs initially earthquake comprehensive prediction system of data storage, and introduces briefly basic model of earthquake comprehensive prediction system of data storage and makes an expectation of its applied potential.
