In this lab, we revisit the complete database design journey and clearly connect the dots between the three major database models. This session is designed to strengthen your understanding before moving further into implementation. 🎯 What This Video Covers 🔹 1. Refreshing the Three Database Models We revise the complete database design process: Conceptual Model – ERD and related concepts Logical Model – Relational Data Model Physical Model – Implementation using SQL You will clearly understand where each model fits in the database design process. 🔹 2. Revising the Relational Data Model We revisit the core components of the Relational Data Model: Relation Tuple Attributes Primary Key Foreign Key These are the building blocks of relational databases and are essential for SQL implementation. 🔹 3. Transitioning from Conceptual to Logical Model One of the most important parts of this lab: ✔ Understanding how we move from ERD (Conceptual Phase) ✔ To Relations/Tables (Logical Phase) ✔ How entities become tables ✔ How relationships are converted into foreign keys This is where database design becomes structured and practical. 🔹 4. Practical Example Activity We solve a step-by-step example: Given an Entity Relationship Diagram (ERD) Converting it into a Relational Data Model Creating proper relation schemas This activity helps students practically understand how design transforms into structured tables. #CS403P #CS403ShortLEcture #DatabaseManagementSystemLabs #CS403 #DatabaseManagementSystem #RelationalDataModel #ERD #ConceptualModel #LogicalModel #VirtualUniversity #MKK
