Consider the following database for projects in a class:

• Student(sid, name, dept)
• Project(pid, topic, budget)
• Team(sid, pid)

Relation Student contains a row for each student with a unique id, student name, and the department of each student. Each row in relation Project holds the unique id of a project, the topic area the students will be working on, and the estimated budget for the project. Finally, the table Team captures the assignments of students to projects.

Which table has a foreign key?
