Question

Create a Crow's Foot ERD Model for a Train Station with these entities. I already did the ERD Diagram!

What are the Cardnitalities in the Diagram and give me an explanation for the Relationship?

Entities:

  •  Train
  •  Station
  •  Schedule
  •  Passengers
  •  Route
  •  Stop 
**ER-Diagram:** ### Description The ER (Entity-Relationship) diagram visually represents the relationships between different entities in a system. Here we describe each entity and their relationships as presented in the given diagram. ### Entities and Attributes: 1. **Station** - **Attributes:** - `Stn_ID` (Station Identifier) - `Stn_NAME` (Station Name) 2. **Train** - **Attributes:** - `Tr_id` (Train Identifier) - `Tr_No` (Train Number) - `Stn_ID` (Station Identifier) 3. **Passengers** - **Attributes:** - `P_id` (Passenger Identifier) - `P_Name` (Passenger Name) - `Tr_id` (Train Identifier) 4. **Stop** - **Attributes:** - `Stop_id` (Stop Identifier) - `Stop_Name` (Stop Name) - `Route_id` (Route Identifier) 5. **Route** - **Attributes:** - `Route_id` (Route Identifier) - `Route_Name` (Route Name) 6. **Schedule** - **Attributes:** - `Scdl_id` (Schedule Identifier) - `Scdl_date` (Schedule Date) - `Tr_id` (Train Identifier) - `Route_id` (Route Identifier) - `Scdl_Route` (Schedule Route) ### Relationships: 1. **Station and Train:** - A Station **has** multiple Trains (1:M). - Train is identified by `Stn_ID` of the Station it is associated with. 2. **Train and Passengers:** - A Train **has** multiple Passengers (1:M). - Each Passenger is associated with one Train (Passenger is identified by `Tr_id`). 3. **Stop and Route:** - A Route **has** multiple Stops (1:M). - Each Stop is identified by `Route_id` of the Route it is part of. 4. **Train and Schedule:** - A Train **has** one Schedule (1:1). 5. **Schedule and Route:** - A Schedule **has** one Route (1:1). ### Detailed Explanation: The ER diagram illustrates the structure of a railway system. Each station can have multiple trains. Each train can carry multiple passengers
