ABSTRACT:: 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. The current state of the Tioga implementation
is also described.
