What is Data Independence?

Data independence means that "the application is independent of the storage structure and access method of data". In other words, the ability to change the schema definition in one level should not affect the schema explanation in the next higher level.

Two types of Data Independence:

 Physical Data Independence: Modification in physical level should not influence the logical level.

 Logical Data Independence: Modification in logical level should influence the view level.
