Abstract

A flowgraph system controls and tracks computer programs and data sets for a computer-aided design (CAD) task. The programs in the CAD task and their respective data set requirement are visually displayed as a flowgraph with which the user interacts to select input data sets and initiate program executions. The flowgraph provides the user with an indication of data flow and the progress of the CAD task.
