VISC方法在水文数据库中的应用──兼谈大型数据库扫描检索系统的设计

Application of VISC to Hydrological Database──Scanning Retrieval System Design of a Large-scale Database

ＶＩＳＣ方法是计算机应用领域近年来发展起来的一种新的交互技术。该方法把不直观的数据信息转换为直观图形，借助于视觉媒介，从而使人眼与人脑紧密结合，完成对信息的分析与处理。本文通过对水文数据库结构的分析，介绍了ＶＩＳＣ方法在水文数据库中的应用，从其扫描检索系统的设计入手，技巧性地处理了设计中的一些关键问题。实例验证表明，ＶＩＳＣ方法能极大地提高大型数据库的“透明度”，使人机界面的友好性得到加强，不失为一种处理庞大数据库的好方法。

Method of Visualization in Scientifilc Computing(VISC)is a kind of new transfer technolo-gy developed in recent years in field of application of computer,which can transfer unvisual data into vis-ual graph and will result in a close combination of human eyes with brain by means of vision medium to per-form data analysing and processing.This paper introduces the application of VISC to hydrological database.Starting with the designning of the scanning retrieval system,it has soled some key design prob-lems.The cases indicate that the VISC can greatly improve the transparency of a large-scale database and strengthen the user interface as a good method.
