Allowed and Disallowed Resources

• Examples and sample code found here: https://josephus.hsutx.edu/classes/db/source/
• The SQL handout provided in class and also available here: https://josephus.hsutx.edu/classes/db/source/sql.pdf
• A text editor (or VSCode) that provides syntax highlighting. You MAY NOT USE an extensions to such editors/IDEs that produce code.
• The phpPgAdmin front end to your personal database (login is here: https://csci.hsutx.edu/phpPgAdmin/
• Video instructions provided in Canvas as part of this course. You MAY NOT USE any other video resources.
• Any handouts provided by the instructor as part of this course.
• Your own course notes
• Your instructor
• Discussions about the assignment with other students as long as you never look at the code produced by another student and you never receive instructions about solving the homework. That is, discussions need to be about concepts and understanding the technologies and not about how to solve the particular problem posed in this assignment.

You may NOT use/access:

• Resources not expressly listed above, including, but not limited to, the following ...
• Source code not provided as part of this assignment. (Obviously, this includes, but is not limited to, source code written by other students whether current or in the past).
• Code-generating tools (of which ChatGPT is one example).

Failure to abide by these guidelines will result in a zero for the assignment and the incident will be reported to the university provost as a violation of the university academic integrity policy. A second incident of academic dishonesty (whether from this course or another computer science course) will result in an F in the course.

Description

Follow these steps as you complete this assignment:

Create a main menu

that will include the following options:

• Make a Reservation
• Cancel a Reservation
• List Current/Upcoming Reservations
• Display Revenue for Current Month
• Exit Program

The menu should be displayed when the program is run and should be placed in a loop to repeat until the user chooses to exit the program.

Make a Reservation

To make a reservation you'll need to:

1. Get the next reservation id using nextval.
2. Display a list of customer and get the customer id from the user.
3. Get a reservation date from the user. (Perhaps use Java Date object).
4. List open rooms for the given date.
5. Get list of rooms for reservation from user.
6. Insert entries into reservation table and room_reservation table.

NOTE: To view customers and open rooms you can/should use the displayQuery() method you wrote in the previous assignment.

NOTE: Be aware a SQL injection concerns.

Cancel a Reservation

List existing reservations and have user select a reservation id. Then delete the appropriate reservation. NOTE: What happens to entries in room_reservation when they cancel?

List Current/Upcoming Reservations

The list should contain reservations from the current day and on into the future. (Do not show reservations in the past). Once you build a proper query this become a simple call to displayQuery().

Display Revenue for Current Month

This query should group revenue for the month by room number so we can see which rooms are generating the most revenue. This is another call to displayQuery().
