ER DIAGRAMS
Budget: ₹600 – ₹1,500 INR
Need to design ER Diagrams
1. Identify the entities in the application. List each entity with a short definition about it.
Hint- They can be derived from the scenario and from business rules.
2.Create two E-R diagrams for the information system using Crow’s foot notation. One diagram (logical model) should show all entities and relationships including many-to-many relationships. The second diagram (implementation model) will include all the entities in the first diagram. In addition, it will have bridge entities that replace many-to-many relationships. Do not list attributes on the ERDs.
