ABSTRACT:: In [STON93] we proposed a visual programming
system called Tioga. The Tioga system applies a boxes 
and arrows programming notation to allow nonexpert users
to graphically construct database applications. Users 
connect database procedures using a dataflow model. 
Browsers are used to visualize the resulting data.

This paper describes extensions to the Tioga browser
protocol. These extensions allow sophisticated, flight-
simulator navigation through a multidimensional data 
space. This design also incorporates wormholes to allow
tunneling between different multidimensional spaces. 
Wormholes are shown to be substantial generalizations
of hyperlinks in a hypertext system.

These powerful mechanisms for relating data provide
users with great flexibility. For example, users can
create magnifying glasses that provide an enhanced view
of the underlying data.
