Sopwith Coach Hire Database

Sopwith Coach Hire Ltd is a leading provider of coach and minibus hire in West London. The company was founded in 1982 and it has continued with steady expansion over the past 30 years. The company operates a fleet of vehicles which are available for hire. The majority of the company’s clients are local schools within West London that use the vehicles for school trips. . However, vehicles can also be booked for private functions.

The Director has requested the creation of a database system to assist in the more effective and efficient running of the company. The Director has provided the following description of the current system. 

System Overview

Customers

A vehicle can be booked by customers and a customer can book many vehicles.

Details of customers need to be recorded, which include name, address, email address and contact number.

Vehicles

The company has a large number of vehicles that range from a standard six seater MPV to a 49 seater coach.

Table 1 (appendix A) lists the company’s fleet of vehicles. The company has more than one model type of vehicle. The hourly rate for hiring each vehicle is also displayed in this table.

Booking

The company wishes to record details of all bookings made by their customers. This will include detailed information of each trip a vehicle is booked for.

Each customer is charged the hourly rate for each vehicle (you may assume that no discounts are given for long term hire).

Employees

The company employs a large number of employees and details of each member of staff need to be recorded. These details include name, address, home telephone number, date of birth, gender, job description, national insurance number and current annual salary. The majority of employees are drivers but the company also has a number of administrative staff that takes the bookings.

The database must be able to handle driver assignments. Each hired vehicle requires a driver. A second driver is required in the following situations; (1) If the driver cannot have a break of not less than 45 minutes after each 4.5 hours of driving, or (2) if the driver cannot have a 10 hour break after driving a maximum of 9 hours driving in a day.

Licence

Each driver must have a valid driver’s licence with no penalty points. Details of each driver’s licence needs to be recorded. This will include the licence number and the expiry date.

In order to drive a small passenger-carrying vehicle with nine to 16 passenger seats, a driver must have a D1 code on their licence. To drive any bus/coach with more than eight passengers, a driver must have a D code. Some drivers have only a D1 code and are therefore only allowed to drive the minibuses. Other drivers have both codes on their licences and can be used for any of the company’s hired vehicles. 

Tests 

The company operates a program that involves random alcohol or drug testing. Any driver may be required to take either the alcohol or drug test or both.

Sopwith Coach Hire Ltd is required to keep a complete record of all test types, dates and results for each driver.

C Tasks and Grading

CIS515 Assignment 2: Database Systems and Database Models

The Strayer Oracle Server may be used to test and compile the SQL Queries developed for this assignment. Your instructor will provide you with login credentials to a Strayer University maintained Oracle server.

Imagine that you have been hired as a consultant to assist in streamlining the data processing of an international based organization that sells high-end electronics. The organization has various departments such as payroll, human resources, finance, marketing, sales, and operations. The sales department is the only department where employees are paid a commission in addition to their yearly salary and benefits. All other departments compensate their employees with a yearly salary and benefits only. Commission is paid by multiplying the employee’s commission rate by the total amount of product units sold. You have access to the following data sets:

Employee (EmpNumber, EmpFirstName, EmpLastName, CommissionRate, YrlySalary, DepartmentID, JobID)
Invoice (InvNumber, InvDate, EmpNumber, InvAmount)
InvoiceLine (InvLineNumber, InvNumber, ProductNumber, Quantity)
Product (ProductNumber, ProductDescription, ProductCost)
Department (DepartmentID, DepartmentDescription)
Job (JobID, JobDescription)

Write a two to three (2-3) page paper in which you:

Design a query that will allow the finance department to determine the commissions paid to specific employees of the sales department for the month of December. Note: You will need to generate the tables described above (Employee, Invoice, InvoiceLine, Product, Department, and Job) in order to compare and validate your code. Validated query code must be part of your paper.
Compare the code of the query you designed in Question one (1) to one that would show how much total compensation is paid to each employee for the same month.
Determine and explain the factors necessary to ensure referential integrity.
Create an object-oriented model to show how the tables are interrelated through the use of graphical tools such as Microsoft Visio, or an open source alternative such as Dia. Make sure that you are able to show the relationship types such as 1:M, 1:1, or M:1. Additionally, remember to include the determined factors from the previous assignment requirement. Note: The graphically depicted solution is not included in the required page length.
Identify which data components are the entities and attributes, and the relationship between each using an object representation diagram through the use of graphical tools such as Microsoft Visio, or an open source alternative such as Dia. Note: The graphically depicted solution is not included in the required page length.
Describe how Big Data could be used to assist in the productivity and forecasting of the organization’s products and resources.

This is your final examination which consists of five programming questions.
You are to provide me with a .txt file or a .sql file for supplying the code for each question. Put these in a .zip file and submit them.

1. Use a cursor to retrieve the location number and the city from the locations table. Pass the location number to another cursor to retrieve from the emp_details_view the last_name, job_title and salary for that employees that work at that location.
a. Use the %ISOPEN attribute
b. Use a simple loop
c. Use an EXIT WHEN and a %NOTFOUND attribute

2. Write an exception handler to raise an exception named DUE_FOR_ROTATION
The criteria for raising the exception is if location id is 2700.
If the employee’s location in the em_details_view meets this criteria output 'Due for Rotation'.
Insert a listing of all of the EMPLOYEES that meet this criteria into the employee_analysis table.
You will need to create an analysis table as:
CREATE TABLE location_analysis
(employee_id NUMBER(6) not null,
Last_name VARCHAR(25),
First_name VARCHAR2(20),
Location_id NUMBER(4),
City VARCHAR2(30));
Screenshot #1 Creating the Analysis Table

3. You will be using the EMPLOYEES table in YOUR TABLESPACE. Using a cursor write a block to find the largest salary where the hire date is before ‘ 1-jan-96’ . When you find employees who match this criteria change give them a salary increase of 25%.

4. You will be using the JOBS table in YOUR TABLESPACE. Create a record that incorporates the four columns from the JOBS table. Output the values for a single job on four lines of output.

5. Write a PL/SQL block to print information about a given country.
a. Declare a PL/SQL record based on the structure of the COUNTRIES table.
b. Use the DEFINE command to provide the country ID. Pass the value to the PL/SQL block through a SQL*Plus substitution variable.
c. Use DBMS_OUTPUT.PUT_LINE to print selected information about the country.
d. Execute and test the PL/SQL block for the countries with the IDs CA, DE, UK, US.
