【摘要】 VisualFoxPro(以下简称VFP)程序设计语言是一种面向对象程序设计(OOP)的数据库语言。运用其对山西省"十五数字地震网络工程"临汾台前兆观测项目所产出的数据建立数据库管理系统,并对每一个具体观测手段建立分类子系统,方便用户对观测资料的使用管理,从而实现对每一个观测手段所有数据的快速查询访问及分析处理,以保障日常震情会商和出现紧急震情时分析资料所用,对观测资料的入库管理也有着积极的意义。更多还原

【Abstract】 The programming language Visual FoxPro(VFP) is a of object oriented programmer(OOP) for database.VFP has been applied to build a database management system to manage the data from precursor observation item in the Central Seismological Station of Linfen.The sorted subsystem is built for every observation,which is convenient for the user to use and manage the observation data,to query fast and manage analytically all related data for normal or urgent seismic situation analyzing.It is also significant for inputting observation data into database.更多还原
