It is necessary to show cognition about gis wholly and utilize case tools to improve development efficiency . based on the questions and some research of scholars , we track and research thoroughly in gis according to software engineering idea . we synthesize a whole development idea primarily and express it by uml , meanwhile analyze a multi - resolution data model in detail 基于上述问题和相关学者研究成果,我们按照软件工程开发流程,对gis软件开发进行了较为深入跟踪和研究,并在此基础上初步整理和阐述了一个整体的开发思想,通过使用uml进行规范化地描述,同时具体分析了一个多分辨率的数据模型。
The statistics function of report is one of the most essential and important requirement of the information system for the most part . but the complexities of report format and query sentence lower the development efficiency of report software . at the same time , the modification of database and the continuous alternative of user ' s demands restrict the development of mis 报表统计功能几乎是所有信息系统最基本、最重要的需求,然而复杂的报表格式要求以及繁复的查询语句使得信息系统报表软件开发效率很低,同时,数据库的修改及用户需求的不断变化也制约了信息系统的开发。
Net language and mapinfo mapxtreme 2004 have realized some functions include system management , data management , data update , the model of selecting cultivated land into prime farmland and data export etc . the repeat use rate of code was increased by taking full advantage of . net technology to design the species of every layer ; with the new function of mapxtreme 2004 , the development efficiency is greatly enhanced 系统实现是采用vs . net开发语言和mapinfomapxtreme2004组件开发出了基于gis基本农田信息系统,实现了系统管理、数据管理、数据更新、耕地入选基本农田模型、据输出等功能;系统中设计时充分利用. net技术,设计了各层中的类,提高代码的重率;利用mapxtreme2004的新功能快速开发与gis相关的部分,开发效率大为提高。
This method not only reinforced the development process of gis application system , shorten the development cycle , increased the development efficiency , realized the reuse of software process , but also improved the reliability , maintainability , extensibility of gis application system 该方法不仅加强了gis应用系统开发过程的集成、缩短了开发周期、提高了开发效率、实现了软件过程的复用,同时也提高北京工业大学工学硕士学位论文一了gis应用系统的可靠性、易维护性和可扩展性。
Developing parallel program by our platform will improve development efficiency 30 to 70 percent . it is easy to embody the thought of parallel designers . the platform will help many programmers develop parallel programs easily , also impulse the development of engineer science in many fields , and make network parallel computing more senses 利用本平台进行并行程序的开发,可以使开发效率提高30 70 ,可以十分方便地将并行工作者的设计思想体现出来,从而使得更多的计算机专业人士也能很轻松的开发并行程序,推动多个领域工程科学的发展,使得网络并行计算更有意义。
Simulation technology shall be utilized to simulate the real running of embedded hardware system to enable the software development and system integration implemented on a virtual stage , so as to complete the system model verification and running activity analysis before the manufacture of hardware prototype , avoiding the mutual wait between the software development and hardware development , in order to improve the development efficiency and lower the risks and costs 利用仿真技术模拟嵌入式硬件系统的真实运行,使软件开发和系统集成在虚拟平台上进行,在硬件原型制造前就完成系统模型验证和运行行为分析,避免软硬件开发相互等待,提高开发效率,降低风险和成本。
In this paper , software reuse technology and methodology are investigated . then the character of j2ee design patterns is discussed and summarized based on gof ' s design patterns . two kinds of j2ee design patterns are compared and analyzed . reusable software construction based on j2ee design patterns with high - abstract level is applied to the development of tender . framework and integrated interface have been built to meet the demand of the reusability , transplantability , expandability and high development efficiency in system analysis . the design of the three - tiered framework of tender has been finished 回顾了设计模式的产生、发展历程,介绍了以gof模式为代表的设计模式的概念、作用、选择和使用,总结出j2ee设计模式的特点,对不同来源的j2ee设计模式进行了分析比较;应用j2ee没计模式建立高抽象层次的可复用软件体系架构,并将它应用于电力设备招投标管理信息系统中,从而提高本系统软件的开发效率和质量。
Using design patterns appropriately in object - oriented software emphasizes objects collaboration relationship , improves system maintainability and reusability . meanwhile , it makes system structure simple , elaborate , well understood and enhances development efficiency as well as system performance 恰当地运用软件设计模式,强调了对象之间的公共协作关系,改善了系统的可维护性和复用性,使网管系统体系结构精巧、简洁、易于理解,有效地提高了项目研发效率,综合提升了tmn网管系统的整体性能。
The target of php - struts framework is to provide a web application framework similar to struts framework to php developer . the framework will separate applications " data access code , business logic code , and presentation code . so , applications will improve on development efficiency , reliability , reuse , adaptability and maintainability 本文参考struts框架的实现提出了“模型-视图-控制器( model - view - controller , mvc ) ”设计模式的php实现? ? php - struts框架,它的目标是给phpweb开发者提供一个类似于struts框架那样的web应用程序框架,使得web应用程序的数据、视图、控制相互分离,实现web应用程序的松散的耦合,从而提高web应用程序的开发效率、可靠性、可维护性和可扩展性。
Since software crisis broke out in 60 ' s , people have been puzzled by it . the program ' s reliability and development efficiency ca n ' t fulfil the society ' s need . on the one hand , software errors cause loss of money , time , or even human life ; on the other hand , the useful codes that programmers develop per annum are few 软件的生产效率和可靠性远远满足不了社会发展的需要:一方面,软件故障给人们的生命和财产造成了巨大的损失;另一方面,社会对软件的需求量日益增加,而程序员每年所能开发的有效代码却仍然是少之又少。
