高效数据库应用研究

效率是数据库应用开发过程中经常遇到的问题。为此，对数据库应用中影响效率的相关因素(如大事务、数据库连接等)进行分析，并针对实际电子商务数据库0RACE9I与JAVA应用中出现的问题，提出了解决方案。     

某考试系统评分模块的边界值测试用例设计

边界值分析(Boundary Value Analysis)技术扩展了对等价类中起始和末尾输入值可能性的分析。输入输出数据中很大百分比的功能性错误都发生在这些边界上,或这些边界值的周围。介绍了边界值分析的基本概念和测试用例设计原则,以某考试系统的评分模块为背景,进行了边界值测试用例的设计。     

基于Unix环境下的信息服务平台系统

介绍了在Linux和Unix平台下用c/c (用Socket)编写服务端程序(守护进程)(程序名称为CallServer),在Windows平台下用VC开发信息点播平台(利用ADO访问ORACLE数据库)(程序名称为SendNessage.exe).     

在SQLWINDOWS中建立tbIFORM类对ORACLE数据库的访问

在ＳＱＬＷＩＮＤＯＷＳ环境下建立ｔｂｌＦＯＲＭ类，应用该类对ＯＲＡＣＬＥ数据库中的表文件按指定的检索条件，把多个表文件中的数据检索出来，并可对检索出来的数据进行编辑。

Dynamic Data Exchange for Collaborative Design Based on Internet

The dynamic data exchange is the key to the realization of the collaborative design based on Internet. The features of data for collaborative design based on Internet are analyzed. The data transformation, the data transmission and the data transaction of collaborative design based on Internet are researched. The system configuration and organization mode of dynamic data exchange for collaborative design Internet-based are developed, in which, STEP serves as the product data exchange standard, and ORACLE is the kernel database of the system, so that each of the CAD systems can synchronously access the ORACLE database, share and exchange the design information. The STEP-ORACLE serves as the organizing mode of dynamic data exchange for the collaborative design based on Internet, which realizes the real-time exchange and consistency of the dynamic data between the different platforms and CAD systems.
