PB在仪表管理中的应用

摘要

PB is a visualization, short development cycle proscenium database development tools, more suitable for engineering staff to design a variety of data management system, such as water management system, with electric management system, public transportation IC card management system. The paper uses the drop-down list in the PB were studied, and puts forward the drop-down list for the realization method of using several. The practice shows that the method has the simple and practical characteristics.%PB是一种可视化的、开发周期短的前台数据库开发工具，比较适合工程人员设计各种数据管理系统，例如用水管理系统、用电管理系统、公交IC卡管理系统等。文章对PB中下拉列表的使用方法进行了研究，并提出了几种使用下拉列表的实现方法，实践表明这些方法具有简单实用的特点。
