Definition Edit

Data independence is "a clear separation of programs from data."[1]

Overview Edit

"Database systems provide two forms of data independence termed physical data independence and logical data independence. . . . The pain of the Y2K (converting from 2-character to 4-character years) taught most organizations the importance of data independence."[2]
