Business rules - Write Business rules to create ERD 
2. Entities and Attributes - List Entities, Attributes - Include all attributes that you believe would be useful

o Create your ER Diagram with Visio/Lucidchart/draw.io or another piece of software.


Hand-drawn diagrams will not be accepted
o Only use “crow’s foot notation”
o ER Diagram should include Entities, attributes, relationships, connectivity and cardinalities.
o When completed, insert your ER Diagram into a Word document either by taking a
screenshot of the diagram and pasting it in the word document, or by exporting the diagram as an image and the inserting it in the word document

Flight

The business rules from the case study are;

  • MPloy airline has many flights.
  • A flight has many passengers on board.
  • A flight uses one and only one airplane.
  • A flight has one and only one pilot who flies the single plane.
  • The airline has many maintenance procedures that are done on airplanes.
  • A maintenance event involves one airplane undergoing one procedure.

Entities and attributes

Based on the business rules and the case study, the following entities with their attributes can be derived;

  • Flight (flightNO, date, departureTime, arrivalTime, pilotNO, serialNO)
  • Passenger (passengerNO, name, address, telNO)
  • Flight_passengers (passengerNO, flightNO, fare, reservationDate)
  • Pilot (pilotNO, firname, lastName, dob, dateOfHire)
  • Airplace (serialNO, model, manufacturer, yearBuilt)
  • Procedure (procedureNO, procedureName, frequency )
  • Maintenance_event (eventID, location, duration, procedureNO, serialNO)
