Abstract: The data visualization systems and methods of this invention provide a powerful tool for visualizing multi-dimensional databases. In one exemplary embodiment, the data visualization systems and methods of this invention visualize pivot tables using two novel visual metaphors: a single measure perspective consisting of linked bar charts and a multiscape landscape visualization; and a anchored measures perspective for displaying several measures simultaneously. The data visualization systems and methods of this invention usefully display much larger pivot tables than is possible using conventional interfaces and provide the ability to navigate through complex cubes to identify important structures. In various exemplary embodiments, the data visualization systems and methods of this invention attach to MS Excel™ as an add-on, access pivot tables directly from SQL Server 7.0, and integrate with MS Office.

Abstract: A software visualization technique allows a software application or portfolio to be visually analyzed to determine the extent and depth of problems raised when converting an existing software application or portfolio to make application- or portfolio-wide revisions, such as those needed to respond to the year 2000 problem or the conversion to Euro currency. The software visualization technique first generates or inputs statistical data on a number of different software metrics and statistics about the conversion process, such as the data or currency dependent lines of program code, the types of affected code lines, and the sizes and complexities of the systems, subsystems and programs of a software application and of the applications forming a portfolio. These metrics and statistics are then used to alter the appearance of various views of the software application, systems, subsystems, programs individual lines of the programs generated by various visualization tools of the software visualization technique.
