PAGE PAGE 基于Web技术的外汇牌价自动发布系统设计 ——数据的提取、导入及更新 年06月10日 基于Web技术的外汇牌价自动发布系统设计 ——数据的提取、导入及更新 摘 要：一般地,一国货币汇率稳定,能构造良好的国际投资环境,吸引外资流入,从而使该国国际储备增加；反之,则导致资本外流,外汇储备减少.当一国的汇率变动导致出口大于进口时,则外汇收入增加,外汇储备增加。所以，这一基于Web技术的外汇牌价自动发布系统的设计则可以为广大用户带来方便。 在本设计中，利用VB开发平台提供的强大能力，以强大的带有自动分析结果的编辑器来生成记忆数据，以流行的INI文件格式来储存记忆库，以表格方式显示记忆库，以强大的ADODB新型数据库访问平台来保存结果，以流行的Access数据库来保存数据，使系统具备极强的可扩展性和实用性。程序经过验证可以分析各大银行的外汇牌价表上的数据，也可以分析其它网页的数据。 在本设计中，主要是能顺利实现对某些重要数据的提取、导入、手动更新和自动更新的功能，并且能够在相应的Led屏上显示出来，以供广大用户作参考。 关键词：外汇牌价；VB 6.0；界面设计；INI文件；ADODB；Access 2003 The design of the foreign exchange rate auto-issue system based on the Web ——abstracting, inputting and renewing of the data Abstract: Generally, the stable exchange rate of a country can build a good invested environment and absorb foreign capital people, thus, it can increase its national store for future use. Otherwise, it can cause capital flight, and reduce its foreign exchange reserve. When the exportation is more than the importation caused by exchange rate changing, both its foreign exchange income and its foreign exchange reserve will increase. Therefore, we call to mind that completing this automatic issue system design based on Web technical foreign exchange rate can bring more conveniences. In this design, using the formidable ability which provided by VB development platform, producing the stored data by the automated analysis result editor formidable, storing up the memory storehouse by the popular INI document format, demonstrating memory storehouse by sheet, preserving the result through visiting the platform by the formidable ADODB new database, and preserving the data by the popular Access database in order to make the system have the great extendibility and the usability. The procedure may analyze each bank after the confirmation in the foreign exchange rate table data, and it may analyze other homepages the data as well. In this design, we mainly can realize to ext
