Logical vs Physical Data Independence | DBMS Module 1 | BCS403 | VTU Database Management System
Welcome to another lecture of Database Management System (DBMS) for VTU 4th Semester (BCS403).
In this lecture, we will discuss one of the most important Module 1 questions:
"Explain the difference between Logical and Physical Data Independence."
Data Independence is one of the fundamental concepts of DBMS that ensures changes at one level of the database do not affect other levels. In this video, we will clearly understand the differences between Logical Data Independence and Physical Data Independence using a comparison table, real-life examples, and easy explanations according to the latest VTU syllabus.
This question is frequently asked in Semester End Examinations (SEE), Internal Assessments (CIE), and Previous Year Question Papers (PYQs).
