CAREER: A Model For Designing Adaptable Software Components

9733660 Heineman这项研究专注于设计软件组件的新技术，这些组件提供了一种适应其行为的机制。组件重用的传统方法受到限制，因为组件必须完全满足应用程序构建器的需求，然后才能重用。这项研究提出了一个新的方向，认为只有当应用程序构建者能够调整软件组件以满足他们的需求时，才会发生基于组件的软件开发。第一个目标是帮助组件设计人员设计和实现高度可重用的组件。本研究提出的独立于语言的解决方案同样适用于用C、C++或Java编写的组件。第二个目标是提供一种体系结构描述语言，用于根据目标应用程序的需要指定对各个组件的适配。第三个目标是构建一个设计工具，帮助用户从可适应的组件组成应用程序。第四个目标是定义一种重新工程方法，用于将现有的遗留代码改造为可适应的组件。最后一个目标是培训我们的学生设计高度可重复使用的软件组件并使用软件组件构建应用程序。这项研究将极大地提高从独立实现的软件组件创建大型复杂系统的能力。***

9733660 Heineman This research focuses on novel techniques for designing software components that provide a mechanism for adapting their behavior. Traditional approaches to component reuse are limited in that a component must exactly meet the needs of an application builder before it can be reused. This research proposes a new direction by suggesting that component-based software development will only occur when application builders can adapt software components to suit their needs. The first objective is to aid component designers in designing and implementing highly reusable components. The language-independent solution proposed by this research applies equally well to components written in C, C++, or Java. The second objective is to provide an architectural description language for specifying adaptations to individual components as needed for a target application. The third objective is to construct a design tool that helps users compose applications from adaptable components. A fourth objective is to define a reengineering methodology for retrofitting existing legacy code into adaptable components. A final objective is to train our students in designing highly reusable software components and building applications from software components. This research will greatly increase the ability to create large, complex systems from independently implemented software components. ***
