What is a database? A model of reality
When to use a Database Management System (DBMS) to make a model?
DBMS are good for data intensive applications, some applications are process intensive applications. Those applications data intensive where there are a lot of data flowing between memory and secondary storage and/or where a lot of data are communicated between the user und the application. This is the case, that when the join field is a key as it is here, there is no way of blowing duplicates in the Email Colum on the right with the Email column on the left.
