Providing Data Management Support for Scientific Visualization Applicationa

我们提出了一个数据库管理系统的用户界面范例，它是由科学可视化应用驱动的。我们的图形用户界面包括用于数据库访问的“方框和箭头”表示法和通过信息空间移动的飞行模拟器模型。我们还提供了指定不同类型和分辨率的数据抽象层次结构的方法，以便支持“缩放”功能。描述了对该系统的底层DBMS支持，包括将查询计划编译为megaplan、用于数据缓冲的新算法以及保证数据传输速率的规定。该提案需要资源来继续探索这些主题，并构建我们的想法的原型实现，我们将其命名为Tioga。

We present a user interface paradigm for database management systems that is motivated by scientific visualization applications. Our graphical user interface includes a "boxes and arrows" notation for database access and a flight simulator model of movement through information space. We also provide means to specify a hierarchy of abstracts of data of different types and resolutions, so that a "zoom" capability can be supported. The underlying DBMS support for this system is described and includes the compilation of query plans into megaplans, new algorithms for data buffering, and provisions for a guaranteed rate of data delivery. This proposal requests resources to continue the exploration of these topics and to build a prototype implementation of our ideas, which we have named Tioga.
