A Graphical, Database-Querying Interface for Casual, Naive Computer Users

A Data-Flow Graphical User Interface for Querying a Scientific Database

We describe the design principles and functionality of a visual query language called SeeQL that represents data retrieval and analysis operations as a data-ow graph. A query is viewed as a sequence of re-lational algebra and other data transformation operations applied to database tables. The language is well-suited for large-scale scientiic database applications, where data analysis is a majo...

Querying Ontologies: A Controlled English Interface for End-Users

The semantic web presents the vision of a distributed, dynamically growing knowledge base founded on formal logic. Common users, however, seem to have problems even with the simplest Boolean expressions. As queries from web search engines show, the great majority of users simply do not use Boolean expressions. So how can we help users to query a web of logic that they do not seem to understand?...

GUIDE: Graphical User Interface for Database Exploration

This paper describes a system which uses graphics devices as tools to interface to complex databases. The difficulties associated with using query languages for large, complex databases such as some of the statistical databases (e.g., Census data, energy data) are examined, We will describe a system containing features such as subject directories, help messages, zooming facilities to the releva...

Dynamic Maps: An Intuitive Interface for Naive Users of Spatial Database Systems

Many approaches have been used for querying spatial databases, but they rarely distinguish between expert users and “naive” ones. Two main approaches can be considered as interesting ways of querying and interacting with spatial and multimedia data, extended query languages on the one hand, and hypermedia techniques on the other hand. In this paper, we propose a framework for a navigational use...
