Question 5 3 pts SQL is known to be a declarative query language: it allows to express the logic of a computation without describing its control flow. Or put differently: SQL queries describe what to do rather than how to do it. What does this mean in practice? Give an explanation using the following small example query in a few, short, meaningful sentences: SELECT Patients.name FROM Patients, Appointments WHERE Patients.pid = Appointments.pid AND Appointments.date = '01/05/2022¹ As a hint, you could describe some different ways on "how to" compute the answer to this same "what" query.
