چکیده

We present a user interface paradigm for database management systems that is motivated by scientiic visualization applications. Our graphical user interface includes a \boxes and arrows" notation for database access and a ight 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 buuering, and provisions for a guaranteed rate of data delivery. The current state of the Tioga implementation is also described.

Extending a Graphical Query Language to Support Updates, Foreign Systems, and Transactions

In [STON93] we proposed a new user interface paradigm called Tioga for interacting with database management systems. Tioga simplifies the task of building database applications and is geared especially towards the needs of scientific users. We borrow the "boxes and arrows" visual programming notation of scientific visualization systems and allow users to graphically construct applications by us...

VIQING: Visual Interactive Querying

This paper presents VIQING, an environment for expressing queries via direct manipulation of data visualizations. VIQING provides a simple graphical interface for connecting visualizations, and has the expressive power of the basic relational operators select, project and join. VIQING has been implemented in the Tioga DataSplash visualization system to provide a seamless integration of querying...

NaturalSemantics Speci cations

This paper proposes an application of programming environments generation to structured document manipulation. We use the Centaur system as a formal tool to model and implement logical and physical document structure, logical structure editing, layout processing, format conversion, and document queries, for a sample class of documents: scientiic articles including equations and gures. We suppor...
