Create a database in SQLServer for the relational model provided in the HW3- Relational Schema file. Populate your database with some data to test your database. Write the requested queries in SQL. The relational model that is provided is part of the relational model from your HW 2, however it has been simplified. The E-R diagram for this relational model is also provided to you in the HW3_Data Model file

• First create an SQL Server database by right clicking on the databases folder in the Object explorer and selecting the New Database option. Name the database by the initials of your last names and then A3. For instance a database created by Johnson and White would be named as jw_A3.
• Write the SQL statements for creating the tables in your database, specifying data types and field lengths, establishing primary keys and foreign keys, and implementing all the necessary constraints. Save your create statements in a file. Use the same naming convention you used to name your database to name your file.
• In your file also include the following SQL statements
  1. An SQL statement to add a constraint to one of the tables.
  2. An SQL statement to add a column to one of the tables.
  3. An SQL statement to insert data to one of the tables
  4. An SQL statement to modify the data in one of the tables.
  5. An SQL statement to delete a row of data from one of the tables.
• Populate your database with sample data.
• Write the following SQL queries and save them in your file also. Put the question numbers above your queries, e.g. Q1, Q2, Q3 etc. Ensure that your queries are correct and produce the results you expected.

1. What is the average rating for cruise with CruiseSerialNo = 1
2. Which cruises have an average rating greater than the overall average rating? Display cruiseid and average rating.
3. Display the ports visited by the cruise, which has the longest duration. (Display PortName, PortCountry, and CruiseID)
4. List the ships which have not been assigned a cruise yet.
5. What is the average number of cruises that a ship sails? (Hint: write a subquery to calculate the count of cruises a ship sails, then using that as the data source take the average of the count of cruises.)
6. Which port has the highest docking fee?

PLEASE ANSWER ONLY THE SECTIONS THAT ARE DARK COLORED. THANK YOU :)
