System Structure Analysis: Clustering with Data Bindings

This paper examines the use of cluster analysis as a tool for system modularization. Several clustering techniques are discussed and used on two medium-size systems and a group of small projects. The small projects are presented because they provide examples (that will fit into a paper) of certain types of phenomena. Data bindings between the routines of the system provide the basis for the bindings. It appears that the clustering of data bindings provides a meaningful view of system modularization.
