Updated On: May 26, 2025
- Physical model
- ER model
- Semantic mode
- Network model
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The Entity-Relationship (ER) model is primarily used in the conceptual design phase of a database.
It helps to define entities, relationships, and constraints independent of the physical considerations.
