Welcome to GeeksforGeeks! In this video, we'll dive into the world of ER and Relational Models in DBMS. If you're preparing for the GATE 2024 exam or just want to learn more about database management systems, you've come to the right place.

First, we'll explore the basics of Entity-Relationship (ER) models and how they help us to conceptualize database designs. You'll learn about entities, attributes, relationships, and cardinality, as well as some common ER diagram notations.

Then, we'll move on to Relational Models, which form the foundation of most modern database management systems. We'll discuss how they represent data in the form of tables, and how they use primary and foreign keys to establish relationships between tables.
