Create an Entity-Relationship Diagram (ERD) to illustrate the database structure. This system will be designed to handle student inquiries and support tickets. When you are creating a new application the first thing you must do is to understand what is needed. There is no such thing as a small application. A client will never know what they want until they see it. So a good thing to do first is to build an ERD so you can talk with the client and see if it looks like it might meet their need.

Entity-Relationship Diagram (ERD)

The ERD will include the following entities:

• Students: Information about students.
• Tickets: Support tickets raised by students.
• Categories: Categories for different types of issues.
• Ticket Statuses: Statuses of the tickets (open, closed, in progress, etc.).
• Ticket Priorities: Priorities of the tickets (low, medium, high).
• Staff: Information about staff members who handle tickets.

Here is the ERD for the "Student Help Desk System":
