The thing is, QV is automatic linking the tables and I can see the connections in the application. So there is the view I need, if I want to see if there is a connection i.e. between a customer and an article I can select either the customer or the article.
Now the question is 'when do I use joins?' I already have the connection without using joins in QV and I am not sure if (or when) it is better to join tables or just to link them.
When are you using joins and when you are avoiding them?
