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.

我们提出了一个数据库管理系统的用户界面范例，是出于科学可视化应用程序。 我们的图形用户界面包括一个“框和箭头”符号的数据库访问和飞行模拟器模型的运动通过信息空间。 我们还提供了指定不同类型和分辨率的数据摘要的层次结构的方法，以便可以支持“缩放”功能。 该系统的底层DBMS支持的描述，包括编译成megaplans查询计划，新的数据缓冲算法，并提供了保证的数据传输速率。 这个提案要求资源继续探索这些主题，并构建我们的想法的原型实现，我们将其命名为Tioga。
