Index coding: a compression technique for large statistical databases

Abstract: Index encoding is a compression technique that involves the substitution of numeric codes for data values. Current methods of index encoding are suited only for attributes whose underlying domains are small or static. In this paper, general methods to encode dynamic domains are proposed and analyzed. A practical methodology for their applictition is presented. We also compare and contrast our methods with another that is now being used in a commercial file management system.

Logical and physical modeling of statistical scientific databases

Abstract: This paper describes the major research tasks currently being undertaken at the Database Systems Research and Development Center of the University of Florida in the area of management of statistical databases. It presents the progress made to date and accomplishments related to the following: 1) the development of a semantic association model and its data language for use in statistical/scientific applications, 2) the study of (a) data mapping between a semantic model and the model used by a particular DBMS and between a logical model and its physical implementation, and (b) view integration problems in database design, 3) the investigation of data compression techniques and the development of a general model of database implementation, and 4) the study of parallel algorithms and database machine techniques for the efficient processing of statistical/scientific databases.
