Question - How this is done maybe covered in later lessons however, I would like to know if multiple users can use the same database at the same time?? I ask because with all the relationships, data is updated in several tables. So can one user edit an existing record while another is entering a new customer which will also update across the same records as another user is updating??

Hi Michael,
Record locking takes place to prevent this from happening.
