Abstract

Two of the major problems with currently available software design tools are that they require too much detail too early in the design process, and that they do little to provide sufficient context for the software designer as the design is taking place. The paper presents a visual interface that addresses these two issues, and that in turn leads to a hew user interface metaphor. The interface is to a set of cooperating expert systems that acts as a non-intrusive, intelligent assistant in the conceptual data modelling phase of database design. The user interface allows the designer to simultaneously work at the abstract level and at the detail level while building the enterprise model from which the database will be generated. The key features of the interface are graphical gestural input, and the spatial maintenance of logical context through a technique of information filtering, using a structure of hierarchical windows. Planned extensions to the interface include user manipulation of a 3-D representation of extended entity-relationship diagrams, interactive control of behavior modelling animations, and the ability to deal with several models at the same time.<>

概念数据建模工具的可视化界面

当前可用的软件设计工具的两个主要问题是，它们在设计过程的早期阶段需要太多的细节，并且在进行设计时，它们很少为软件设计人员提供足够的上下文。本文提出了一个可视界面，解决了这两个问题，进而引出了一个新的用户界面比喻。接口是一组协作的专家系统，在数据库设计的概念数据建模阶段充当非侵入式智能助手。用户界面允许设计人员在构建将从中生成数据库的企业模型时，同时在抽象级别和细节级别进行工作。界面的关键特征是图形手势输入，以及通过信息过滤技术对逻辑上下文的空间维护，使用分层窗口结构。对界面的计划扩展包括用户对扩展实体关系图的三维表示的操作，行为建模动画的交互式控制，以及同时处理多个模型的能力。
