Application programs should not, ideally, be exposed to details of data representation and storage. As you flip the coin, one result does not influence or predict the next outcome at all. The results of a coin toss represent independent binary data. It refers to the immunity of user applications to changes made in the definition and organization of data. When we say a variable is independent we mean that it does not depend on another variable for the same subject. Even if you get five heads in a row, the … The DBMS provides an abstract view of the data that hides such details. The classic example of independent events is flipping a coin. Data independence is the idea that generated and stored data should be kept separate from applications that use the data for computing and presentation.
