PET_OWNER (OwnerID, OwnerLasst Name, OwnerFirstName,

OwnerPhone, OwnerEmail)

PET (PetID, PeeetName, PetType, PetBreed, PetDOB, OwnerID)

Sample data for these tables are shown in Figures 3-27 and 3-28, For each SQL statement you write, show the results based on these data. If possible, run the statements you write for the questions that follow in an actual DBMS, as appropriate, to obtain results. Use data types that are consistent with the DBMS you are using. If you are not using an actual DBMS, consistently represent data types by using either the SQL Server, Oracle Database, or MySQL data types shown in Figure 3-5.

3.7 Write an SQL CREATE TABLE statement to create the PET_OWNER table, with OwnerID as a surrogate key. Justify your choices of column properties.

Write a FancyCar class to support basic operations such as drive, add gas, honk horn, and start engine. FancyCar.java is provided with method stubs. Follow each step to gradually complete all methods. Note: This program is designed for incremental development. Complete each step and submit for grading before starting the next step. Only a portion of tests pass after each step but confirm progress. The main() method includes basic method calls. Add statements in main() as methods are completed to support development mode testing. Step 0. Declare private fields for miles driven as shown on the odometer (int), gallons of gas in tank (double), miles per gallon or MPG (double), driving capacity (double), and car model (String). Note the provided final variable indicates the gas tank capacity of 14.0 gallons. Step 1 (2 pts). 1) Complete the default constructor by initializing the odometer to five miles, tank is full of gas, miles per gallon is 24.0, and the model is "Old Clunker". 2)…
