数据动态监测及可视化管理

How To Scout and Visualize Dynamic Datum

本文设计系统软件实时监测保存在EXCEL表格中的动态数据,并对其进行可视化管理。以VC++6.0为开发工具,结合DDE机制和ODBC思想读取动态数据并构造数据库给以管理。同时,基于动态数据库和MapX控件构造地理信息系统对数据进行专题化显示。文章对其中涉及的关键技术、系统功能和开发步骤作了详述。

This article designs a kind of system to scout and visualize the dynamic datum stored in the EXCEL. And the VC＋＋6.0 programming ianguage assisted with the DDE mechanism and the idea of ODBC is used to read the datum and construct the database to manage them. Then a kind of Geographic Information System is constructed on the basis of the database and the MapX Control to visualize the datum. The key technology , the system＇s function and developing steps are introduced in detail.
