【摘要】 传统的C/S结构是基于PowerBuilder、VB等的开发工具,需要对每一张表设计数据库录入、查询代码,其代码量大,系统测试和升级量大。本文对气田开发数据库八大类163张数据表进行了分级,设计了数据字典,引用美国CodeJock公司的导航菜单代码,用代码重用和继承的面向对象技术设计了通用数据录入模块、通用数据查询模块。系统所设计的代码量小,测试升级方便。还介绍了针对网络时通时断的可靠数据传输方法,并在实际中得到了应用。更多还原

【Abstract】 The traditional C/S structure, based on development tools such as Power Builder and VB, requires the design of data input and code inquiry to every sheet of table, which demands large numbers of codes and is inconvenient in system testing and upgrading. In this research, 163 sheets of table from 8 categories of natural gas field development database are graded and a data dictionary is designed. Meanwhile, by introducing CodeJock′s navigation menu code and Object-Oriented Design in code reutilization, this paper designs the general data input module and general data inquiry module. Compared with the system used beforehand, this one has a small number of codes and is convenient in testing and upgrading. Moreover, this paper introduces a reliable data transmitting method against the instable situation of the network, which has already gained practical application.更多还原
