Program Perspectives: A Relational Representation of Measurement Data

This paper concems the representation and processing of data resulting from the measurement of programs written in high-level programming languages. The value of various "perspectives" of measurement results, especially in languages having many levels of activity, is illustrated. A representation of measurement data based on ideas from relational data bases is presented, in which perspectives can be represented as hierarchically-organized permuted projections of measurement data. Applications described include measurement of Snobol4 and Fortran programs.
