Database Conceptual Design – Conceptual ERD

In this activity, you will analyze a given scenario and manually draw a Conceptual Entity-Relationship Diagram (ERD) using Chen’s Notation. Make sure to:

✅ Identify Entities

✅ Determine Attributes (simple, composite, multivalued, derived)

✅ Define Relationships between entities

✅ Apply correct Cardinality (1:1, 1:M, M:N)

✅ Use proper ERD symbols and notation

I LOVE SQL

Draw a Chen Notation ER diagram for a simple University database consisting of

entities Student, Department, Course, and Instructor. Show suitable relationships with

cardinality and participation constraints.
