Data Independence refers to the ability to modify the schema definition in one level in such a way that it does not affect the schema definition in the next higher level.

The types of Data Independence are:

  • Physical Data Independence: It modifies the schema at the physical level without affecting the schema at the conceptual level.
  • Logical Data Independence: It modifies the schema at the conceptual level without affecting or causing changes in the schema at the view level.
