A company wants to store their invoices in a database. They
already have their customers and articles in that database.
Both customer and article are each identified by an unique
integer value. Please create the SQL statements for
creating the necessary table(s) for storing the invoices in
a MySQL database. An invoice should hold information like
invoice number, customer, date, article(s) and quantity
etc.
