Abstract:

The prototype file design handbook contains extensive quantitative file design discussion. The basic foundation of the discussion is provided by tables and graphs derived from hundreds of actual machine and simulation model runs. These runs take into consideration all the complex characteristics of real-life access methods and thereby insure against oversimplified abstractions which tend to overestimate performance. The file designer can use these tables to obtain quantitative estimates of performance for analogies to his problem and to obtain general information with regard to trends and discontinuities in access method behavior. The text contains discussions of generalizations that appear to be validly derivable from the tables. Finally, in several instances, approximate equations have been provided to further quantify the generalizations for the designer. Author
