You will be completing this list ofbusiness rules.1. To get started, list the names of all entities provided in the business rules above.2. Identify the entities that are related to each other.3. Identify the optionality and plurality constraints on both sides of each relationship,where possible. Indicate where the provided business rules do not provide theoptionality and plurality constraints.4. Create a complete list of business rules. The new list should not add additionalentities, but should specify the optionality and plurality constraints for both sides of allrelationships. Make reasonable assumptions to create the list and state yourassumptions. There is no provably “right” list of assumptions.5. Create aconceptualentity-relationship diagram using Crow’s Foot notation thatreflects your list of business rules. You may use Microsoft Visio Pro or another similarlycapable drawing application to produce your ERD.
