Chapter case from book "Systems Analysis and Design".

Chapter Case- Scenic Routes

Scenic Routes operates a bus company that specializes in travelling on secondary roads, rather than Interstate highways. Their slogan is: "It Takes a Little Longer, But It's Scenic." The firm needs to update its passenger reservation system.

Background

Data items must include reservation number, Route Number, Date, Origin, Destinations, Departure Time, Arrival Time, Passenger Name, and Seat Number. For example, Route 97 leaves Monroe, VA, daily at 8:00 A.M. and arrives in Spencer, VA, 100 miles away, at 11:00 A.M. Scenic wants to use an alphabetic reservation code, similar to the codes that airlines use.

Tasks-

1. Identify the entities and their relationships. Then create an ERD for the reservations system.

2. Create 3NF table designs for the system.

3. For each of the entities identified, design tables and identify the possible candidate keys, the primary key, a probable foreign key, and potential secondary keys.

4. Use sample data to populate the fields for three records.
