A functional view of data independence
Michael R Stonebraker · 1976
Many researchers have used the term “data independence” without indicating a precise meaning. One common definition is—the isolation of a program from considerations of the data which it processes [1,2].Another is—the ability of an applications program to execute correctly regardless of the actual storage of its data[3,4].Although these suggest the general concept, a precise framework is clearly needed. The current paper provides such a framework and explores its ramifications.
