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(More)
This paper reports on user experience with Tioga, a DBMS-centric visualization tool developed at Berkeley. Based on this experience, we h a v e designed Tioga-2 as a direct manipulation system that is more powerful and much easier to program. A detailed design of the revised system is presented, together with an extensive example of its application.
In this paper we present a new architecture for visualization systems that is based on Data Base Management System (DBMS) technology. By building on the mechanisms present in a next-generation DBMS, rather than merely on the capabilities of a standard file manager, we show that a simpler and more powerful visualization system can be constructed. We retain(More)
This paper describes extensions to the Tioga flight-simulator browsing protocol presented by Stonebraker et al. (1993a). These extensions allow users to navigate a multidimensional data space using sophisticated zooming capabilities. This design also allows users to move easily between different multidimensional spaces. Tunneling between different data(More)
