A Components Library System Model and the Support Tool

Component-based development needs a well-designed components library and a set of support tools. This paper prasents the design and implementation of a components library system model and its support tool UMLCASE, A set of practical CASE tools is constructed. UMLCASE can use UML to design Use Case Diagram, Class Diagram etc. And it integrates with components library system. Key words component technology - components library - support tool for components library CLC number TP 311. 52 - TP 311 Foundation item: Supported by the National Natural Science Fundation of China (60373072) and National 973 Program (2002CB312001)Biography: MIAO Huai-kou (1953-), male. Professor, research direction: formal methods, software engineering and automatic reasoning.

Simulation Laboratory and Critical Appraisal of Development Tool

In order to carry out the different network question meaning the research to like the protocol interaction,the network dynamics' function,the measurable quantity waits for it is the necessary delivery is including.Thus,the network simulation may use in showing or quite interesting network performance and so on.Part two aim is provides the type of development tool,including consider such as cost,ease to use and limitations of software packages.The report is to meets the system specification requirement immediately the available component.

如何实现软件开发工艺的突破?谈组装软件-应用软件开发的新技术、新工艺、新工具

该文对软件产业的发展及近来在美国业界的发展趋势进行了深刻的分析,从传统制造业的特性与发展史来分析现阶段的软件产业发展的主要矛盾,得出了未来十年对软件产业起决定性作用的将不再是技术,也不是单元劳动力成本,而是工艺的结论。在此基础上,该文首次提出“组装软件”的新工艺,并对软件开发自动化做了进一步的探讨。“组装软件”是在现有成熟技术的基础上发展起来的一种应用软件开发新工艺。利用这种新工艺及其相应的开发工具来开发应用软件,其成本将是传统开发方法的零头,开发周期也将缩短90%以上;新工艺开发的系统可适应需求的随时变化,从而大大降低应用系统的二次开发和维护成本(总拥有成本),这将对软件产业带来一种革命性的变化。超短开发周期的开发工艺对于建立处理象非典这种突发性事件的信息系统非常有意义。
