Physical Data Independence
- Making changes to the physical schema without changing the logical schema is called physical data independence.
- If we change the storage size of the database system server, it will not affect the conceptual structure of the database.
- It is used to keep the conceptual level separate from the internal level.
- This happens at the logical interface level.
- Example – Changing the location of the database from C drive to D drive.
What is Data Independence in DBMS?

In this article, we will learn in full detail about data independence and will also see its types. If you read it completely, you will understand it easily.
