Computer System Support for Data Analysis.
Greenfeld, Norton Robert
Data analysis and supporting computer software systems are studied. The idea of data analysis as an experimental science involving data-gathering and theory building is developed. Language's role as a determinant of meaningful theory and the informativeness of a language and data base pair are studied, along with the static and dynamic aspects of data analysis. Computer systems useful for data analysis are surveyed, with special attention paid to language restrictions. Next, the Rapidly Extensible Language (REL) data analysis system is discussed and its major limitations considered. The problem of paging of data is investigated and two classes of data structure representations are reviewed. Following this, the implications of data representation for fundamental process of data analysis--the quantification of variables--are presented. Two implications of quantification are compared, with indications found that the use of the "lable class" method results in orders of magnitude improvement over the low predicate calculus technique.
