I have a question
I am currently a reporting system, the function of this system is to control the printing of certificates, that is, if you print one or more times, I need to get that control.
To make this system need two tables: The table has 40 field course and the student table has 30 fields. To print the certificate from the table need 12 field course and the student table 13 fields. I create my own tables, but I want to know whether it is necessary to bring those 25 fields to my tables, for example: One thing that I bring to my system tables is: names, but that figure is a master table, my question is if I should bring me to my system
1. code and the names (with this option I am repeating data)
2. code and then refer to the master table (with this option do not repeat)
