Abstract

We designed and implemented a prototype software development environment based on software component composition. Our software development environment, the Entity-Relationship Software Development Environment (ERSDE), uses extended entity-relationship diagrams (EERDs) as templates of executable programs. An EERD represents the component types and the relationship types among them within an application domain. The graphical editor of the ERSDE uses an EERD as a menu in constructing application software. An EERD used as a menu can enforce legitimate patterns of relationships among software components, in addition to providing an intuitive view of available components and possible relationships among them. Furthermore, as the ERSDE uses structural active objects as the components of a program, we can obtain an executable program if those components are instantiated and interconnected as dictated by an EERD. Two experiments conducted confirmed the effectiveness of our approach.
实体关系软件开发环境
设计并实现了一个基于软件组件组合的原型软件开发环境。我们的软件开发环境,实体-关系软件开发环境(erde),使用扩展实体-关系图(eerd)作为可执行程序的模板。EERD表示应用程序域中的组件类型和它们之间的关系类型。erde的图形编辑器使用EERD作为构建应用软件的菜单。作为菜单使用的EERD除了提供可用组件和它们之间可能的关系的直观视图外,还可以强制执行软件组件之间关系的合法模式。此外,由于erde使用结构化活动对象作为程序的组件,如果这些组件被实例化并按照EERD的指示相互连接,我们就可以获得一个可执行的程序。进行的两个实验证实了我们方法的有效性。
