【摘要】 模型转换是模型驱动开发中的核心技术.为了解决复杂的转换问题,需要将多个相对简单的转换组合起来构成组合转换.目前存在多种转换技术,它们之间存在异构性,阻碍了组合转换的实现.首先分析实现组合转换的必要条件,进而提出一个组合转换模型,其中主要包括公共类型表示、公共模型表示、公共转换描述和组合转换定义语言等部分,用以实现支持多种转换技术的组合.另外,还介绍了一个组合转换平台的设计与实现,并通过一个案例说明所提方法及工具的可行性.更多还原

【Abstract】 Model transformation is the key technique of model driven development.To handle difficult problems,it is necessary to combine smaller transformations into a complex one.Due to the heterogeneity among different transformation techniques,it is difficult to combine them together.The paper analyzes four essential conditions for composite transformations.Next,the paper proposes a composite transformation model,which consists of common type representation,common model representation,common transformation description,and composite transformation definition,in order to realize composite transformations.The paper also introduces the design and implementation of a transformation composition framework.A case study is also presented to illustrate the feasibility of this approach.更多还原
