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.

Abstract: A method and apparatus for visually displaying structural characteristics of a large database for visualizing areas where new developments may be added, or finding places where old developments may need to be re-structured or replaced. This method and apparatus shows the entire structure without showing the entire semantics, which would be too much information. Semantic information is available in other windows that can be opened after the focus of the analysis is selected. After selection, the semantic information is displayed in a focused manner also. This is accomplished by referencing the selected relation to the location of that relation in the database specification or in the relational data base management system (RDBM) application code.
