Data window technology based on view of power builder is used to strengthen the independence of dqas during the designing of dqas 在dqas的设计开发中，采用了powerbuilder基于视图的数据窗口技术以增强dqas的独立性。
Some technical knowledge as oop ( object orient programming ) , sql ( structured query language ) , datawindows are also explained in this paper 对于一些技术知识，如oop (面向对象程序设计) 、 sql (结构化查询语言) 、数据窗口等也加以闸述。
Then in term of the designed system frame , it uses the selected hardware and software environment of exploiting system to design ali kinds of the visible objects and the application 然后确定系统环境的硬、软件支撑，按照设计好的系统结构，对系统菜单、窗口对象、各控件按钮、数据窗口对象等可视化界面和各功能模块的程序进行设计。
The main purpose for paper why propose rebuilding design conception is remedy this limitation , then design relevant framework and analyse problems including rebuilding design of database . dynamic data window construction and so on 并设计了相应的构造式框架结构，分析了实现时要解决的数据库重构设计、动态数据窗口构造等问题以及解决思路。
System integration technique is used in the design of the system , and satisfactory effects result from the extensions of the function of the datawindow and the data pipeline witch fetch up the limitation of the powerbuilder in the creating chinese report and transferring data 在系统设计中，采用了系统集成技术，并通过扩展数据窗口和数据管道功能弥补了powerbuilder在创建中文报表和数据转移上的不足，取得了令人满意的效果。
To avoid unnecessary performance penalties , expression evaluators should not examine the attributes on the display proxy of the type unless the type is expanded , either through the user clicking the plus sign next to the type in a data window , or through the application of the 为避免不必要的性能损失，表达式计算器不应通过以下两种方式来检查类型的显示代理上的属性（除非该类型已展开） ：通过用户单击数据窗口中类型旁边的加号( + ) ，或通过应用
While the adoption of the b / s mode simplifies the developing of client software , however it raises the requirement for data security , and the function of complex windows for data exchanging is difficult to fulfill . on the basis of the comparison and discussion of the developing and running modes of all kinds of information system , this paper is devoted to the study of key techniques of information system in the research of " graduate education & management information system ( gemis ) " . on the basis of the comparing and analyzing of the modes of information system from the aspect of engineering practice , a novel c / s and b / s combined mode is presented 本文在对目前各种信息系统开发运行模式比较和探讨的基础上，结合“研究生教育管理信息系统”课题的具体开发实践，对信息系统的关键技术进行了深入的理论和实践研究：从工程实践的角度对信息系统多种开发运行模式进行分析和比较；提出了一种新型的c s 、 b s混合信息系统模式；对不同信息系统模式尤其是c s和b s混合模式下数据库访问方式进行阐述；对powerbuilder8 . 0的特点、 asp脚本语言的特点进行了介绍；研究了基于b s模式下利用asp脚本语言实现信息系统的数据库发布技术；针对研究生教育管理工作的特点，结合信息系统开发的相关知识如数据库设计、数据管道、数据库并发控制、数据窗口设计、应用窗口设计等技术，实现了“研究生教育管理系统” ，并得到了实际应用。
In this thesis , guangzhou electromechanical mechanic school mis is researched , combined with the theories of data model , function dependence and relation standardizat - ion , system databases and standardized data tables are devised . according to the design idea of the application , the utility , the standardized management and the modern informat - ion management mode , system integration , general layout , data conformity and application research are carried through , the school mis based on c / s structure is realized by programming , a new and universal method of active datawindow is brought forward 本文以广州机电技工学校的管理信息系统为研究对象，结合数据模型、函数依赖和关系规范化设计理论，进行了系统数据库和规范化数据表的设计。依据应用性、实用性、标准化管理的设计思想和现代信息管理模式，对mis系统整体进行了集成、总体规划、数据整合和应用研究，编程实现了基于c / s结构的校园管理信息系统，提出了一种新的通用和独特的动态数据窗口创建技术。
