Karl Database Designer I understand that you are looking to modernize your ballet school? Joan Yes, I feel that I am not up to date with the new technology, and its ruining my business. I want to use the computer to organize my bills, students, schedule and teachers. Karl I understand, but before I can help with that, I need to know how your business works, and then I can design a system that is meaningful to you. Joan What is it that you need to know about the business? Joan I really need information about my students. Sometimes the phone numbers are missing, or the emails are outdated. Also, I would like to keep track of when everyone is paying. All students have a different date for paying the tuition. Also, I would like to keep track of the ballet teachers schedule. Sometimes teachers reschedule classes without me knowing and it causes confusion when I need to cover that particular class. Is there anything else you need? Karl Great, I think I understand. I will jump on it.
