A healthy lifestyle advocacy group is aiming to build a bike-sharing system within a medium-size
metropolitan area. The group has signed a contract with a company to provide the bike-sharing
technology and hardware (bike stations, bikes, network equipment, a server, and bike-sharing software that automates the process of checking out and returning bicycles, and billing customers).
DOCKING STATIONS & BIKES
The docking station provides a limited number of bike parking spots and is characterized by its location, bike capacity, and real-time number of bikes parked. Docking stations have computers running on them, a credit card reader, and a networking module that allows them to be connected to the Internet. The fleet of bikes has also been purchased.
FUNCTIONING OF THE SYSTEM
There are two ways a user can get access to the system:
1) Using her annual subscription ($70)
2) Buying day pass ($5)
Every ride under 30 minutes is free. The user is charged $1 dollar for a ride between 30 and 1 hour, 3 dollars for rides between 1 hour and 2 hours, and a flat rate of 7 dollars for any ride over 2 hours. The users who haven’t returned a bike within 10 hours are billed with a $50 fine.
Design of the Relational Database Structure
Data in IS can be stored in the database. Relational databases is the most commonly used type of database.
Submit the following information in a Word document:
1. Create a table(s) to describe current and historical rides;
2. Write SQL statements that would perform the following tasks:
· Compute the average ride duration for a given user;
· Compute the number of bikes checked out at the given bike station;
Retrieve the list of all currently active users.
