Modification performance and mental models formed during the experiment were examined as a function of design methodology for student and professional programmers. The data suggested that program structure had a much stronger influence on the student programmers. Further, the data showed that where program design led to different mental models, it also led to differences in modification performance. In the data base arena, the focus of the research was on the impact of structuring the information contained in the data base on the retrievability
