摘　　要：创建动态的、可配置和具有自适应能力的应用系统一直是软件开发人员追求的目标,自适应对象模型开发是一种有效的解决方法。自适应对象模型具有描述驱动、最终用户编程和运行时解释执行等特点,其体系结构由元模型、模型引擎和支撑工具组成。首先详细分析了元模型的六个模式,并讨论了模型引擎的原理和支撑工具,分析对开发带来的影响和阐述实现中的问题,最后提出了应用自适应对象模型方法开发的新的应用软件平台———应用件。The rapidly changing requirements and business rules stimulate software developers to make their applications more dynamic,configurable and adaptable.An effective way to meet such requirements is to apply an Adaptive Object-Model.The real power of Adaptive Object-Models lies in description-driven,end-user programming and interpreting at runtime.The Adaptive Object-Model architecture style is composed of metamodel,model engine and tools.Six small patterns to build metamodel are analyzed in detail,model engine to interpret metamodel and tools for end-user to define and configurate object mo-(dels) are discussed.Implementation issues followed by the consequences of Adaptive Object-Models are addressed.A novel platform:Applicationware is proposed,which is derived from the Adaptive Object-Model architectural style and the evolutionary development process.
