Questions about erd templates
What entities are typically included in a smart bus ticketing ER diagram?
Common entities include Passenger, Ticket, Bus, Route, Schedule, Payment, and Driver. The diagram shows how they relate, such as a Passenger purchasing a Ticket for a specific Schedule on a particular Bus.
How do I model seat availability in an ER diagram?
You can add a Seat entity linked to Bus and Ticket, or include availability as an attribute of Schedule. For a many-to-one relationship, each Ticket reserves one or more Seats.
What is the difference between a logical and physical ER diagram for bus ticketing?
A logical ERD focuses on business entities and relationships without DBMS specifics, while a physical ERD includes data types, indexes, and constraints like foreign keys to match your database implementation.
