项目摘要

This research is toward integration of database management systems and visualization systems. Our primary research result is the design and implementation of MWMD, which integrates Khoros, a modular visualization environment with PostgreSQL, an extensible database management system. This system makes it possible for the user and the programmer to makes use of the visual programming interface of Khoros in building database search predicates and formulating queries. In addition to this database programming platform, we have built two advanced database applications in the above mentioned field. The first application searches three dimensional scenes described in VRML, a virtual reality modeling language, by direct and interactive manipulation of queries and query results. The second application helps the users of our campus LAN system obtain quick insights into the possible causes of a systems trouble by visualizing the organization of the networking devices and laying out network traffic data upon the visualization. Besides its apparent motivation, this application has also been intended to be a case study of the systematic construction of information visualizations. Our research also covers the application of the database systems technology to supporting the users of information visualization. GADGET/IV has been designed and implemented so that the user can retrieve cases of information visualizations based on the description of his/her visualization goal. While the approach has been inherited form our previous work, GADGET, which was built for the users of scientific visualzation environments, we have newly built the database of visualization cases, defined the controlled vocabulary, and implemented the user-support functions.

这项研究是针对数据库管理系统和可视化系统的整合。我们的主要研究结果是MWMD的设计和实施，该设计和实现将模块化可视化环境与PostgreSQL（一个可扩展的数据库管理系统）集成在一起。该系统使用户和程序员可以利用Khoros的视觉编程接口在构建数据库搜索谓词和制定查询中。除了此数据库编程平台外，我们还在上述字段中构建了两个高级数据库应用程序。第一个应用程序通过直接和交互式的查询和查询结果搜索VRML（一种虚拟现实建模语言）中描述的三维场景。第二个应用程序可帮助我们的校园LAN系统的用户通过可视化网络设备的组织并在可视化时提供网络流量数据来快速了解系统麻烦的可能原因。除了明显的动机外，该应用程序还旨在成为信息可视化系统构建的案例研究。我们的研究还涵盖了数据库系统技术在支持信息可视化用户方面的应用。 Gadget/IV已经过设计和实施，以便用户可以根据其可视化目标的描述来检索信息可视化的情况。虽然该方法已经继承了我们以前的工作，但为科学视觉环境的用户构建的Gadget，我们已新构建了可视化案例的数据库，定义了受控的词汇，并实现了用户支持功能。
