I would like to see if this database can be improved, and add a relationship between the schedules table and users by means of an intermediate table called appointments.

When a user registers, the data is stored in the Users table. Once you log in, you can request appointments. A schedule is displayed and you select a date, which is saved in the timetable table. And the id and Client field of the table schedules are saved in the table as citations id_cita and nombre_cita respectively.

If the user does not cancel the appointment, and the day of the appointment arrives, this way I keep a table that saves the user, that I can call Client since he / she has attended the appointment. I do not know if the approach is better understood. I consider the table appointments as an intermediate table between users and schedules. The other tables have no relation to any, since they are independent things.
