摘要:

本系统应用微软access数据库系统建立了西北沙尘天气数据库,采用C/S结构在数据库环境下编程,设计了数据挖掘系统数据挖掘机)、资料维护系统、数据接口系统。数据挖掘机实现了一般用户在不了解数据格式的情况下,通过可视化的界面按任意条件对资料进行查询、统计,并通过各种算法对资料进行处理,生成用户需要的资料序列;数据接口系统实现将查询结果以图形、文本文件、绘图格式文件等多种格式输出;资料维护系统实现资料的追加及维护等功。

Abstract:

Using the microsoft access database system, a database of sandstorm in arid region in Northwest China has been created.
We designed system of data mining  (data mining machine), data maintaining ,data querying and data interface by C/S programming
structure under database environment. When normal user doesn't know data format ,the data mining machine can achieve data query-
ing and statistics according to any condition by visual interface ,and process data by all kinds of algorithms and come up with user
needful data SeqLIenCe.  Th1S  System Can Olltpllt qLICrylng TCSLI1tS by graph ,teXt flle ,mapplng flle and  SO On .The new data can he ap-
pended by the data maintaining system easily.

Key words:  sandstorm, database, client server, data mining
