The DEVise framework, implemented in a tool that has been already successfully applied to a variety of real applications by a number of user groups, makes several contributions. In particular, it combines support for extended relational queries with powerful data visualization features. Datasets much larger than available main memory can be handled---DEVise is currently being used to visualize datasets well in excess of 100MB--- and data can be in...

Researching system administration by Eric Arnold Anderson Doctor of Philosophy in Computer Science University of California at Berkeley Professor Dave Patterson, Chair System administration is a phenomenally important, yet surprisingly ignored sub-field of Computer Science. We hypothesize that this avoidance is because approaches for performing academic research on system administration problems are not well known. To reduce the difficulty of performing research, we present a small set of principles that can be used to evaluate solutions, a classification of existing research on system administration, and three approaches to research on system administration that we illustrate with the research that we have done.
