In the context of DBMS architecture, what does the term 'physical data independence' mean?

Step 1: Understand what a database is. A database is a collection of data that is organized in a way that makes it easy to access and manage.
Step 2: Learn about DBMS (Database Management System). A DBMS is software that helps you create, manage, and manipulate databases.
Step 3: Know the difference between physical and logical data. Physical data refers to how data is stored on hardware (like hard drives), while logical data refers to how data is organized and structured in the database (like tables and relationships).
Step 4: Understand what 'independence' means in this context. Independence means that one thing can change without affecting another thing.
Step 5: Put it all together. Physical data independence means that if you change how data is stored physically (like moving it to a different type of storage), it won't change how you access or interact with the data logically (like the tables and their relationships).

Physical Data Independence – The ability to change the physical storage of data without impacting the logical structure or schema of the database.
