In this lecture, we will learn about 3-Schema Architecture in Database Management System (DBMS) in Bangla. This architecture is very important to understand how databases maintain data independence and organize data at different levels.

We will clearly explain:

0:00 - Introduction
4:13 - External Schema
7:53 - Conceptual Schema
10:43 - Internal Schema

This lecture is suitable for:
DBMS beginners
Computer Science & IT students
University / Diploma / Polytechnic learners
