Visual Interfaces for Databases

New approaches to designing a Pivot Table interface ...

"Although visual interfaces and databases are two of the success stories of the computer revolution, their synergy to date has been modest, probably because visual interfaces have focused on human capabilities while databases have focused on efficient query processing. The success of visual interfaces started with the GUI (Graphical User Interface), which supplanted the command line interface by exploiting the power of the human visual motor system. Given advances in graphics hardware in the mid 1980s, research started on Visualization, the use of interactive, visual representations of data to amplify cognition. We will briefly describe Mackinlay’s dissertation, which formalized Jacques Bertin’s design theory, adding psychophysical data, resulting in a system that could automatically design graphical presentations.

In This talk we describe an interface for exploring large multi-dimensional databases that extends the well-known Pivot Table interface. The novel features include an interface for constructing visual specifications of table-based graphical displays and the ability to generate a precise set of relational queries from the visual specifications. The visual specifications can be rapidly and incrementally developed, giving the analyst visual feedback as they construct complex queries and visualizations."   continued ...   (Via Stanford HCI)
