A cornerstone of modern database systems is physical data independence, i.e., the separation of a type and its associated operations from its physical representation in memory and on storage media. Users manipulate and query data at the logical level; the DBMS translates these logical operations to operations on files, indices, records, and disks. The efficiency of these physical operations depends very much on the choice of data representations.Choosing a physical representation for a logical database is called physical database design. The number of possible choices in physical database design is very large; moreover, they very often interact with each other. We attempt to list and classify these choices and to explore their interactions. The purpose of this paper is to provide an overview of possible options to the DBMS developer and some guidance to the DBMS administrator and user.While much of our discussion will draw on the relational data model, physical database design is of even more importance for object-oriented and extensible systems. The reasons are simple: First, the number of logical data types and their operations is larger, requiring and permitting more choices for their representation. Second, the state of the art in query optimization for these systems is much less developed than for relational systems, making careful physical database design even more imperative for object-oriented database systems.
