I am preparing for salesforce developer I certification and ran into a question:
 
A Developer wants to create a custom object to track Customer Invoices.
How should Invoices and Accounts be related to relate that all invoices are visible to everyone with access to the Account?
Of course it’s going to be a master detail relationship
There are two options:
The Invoice should have master detail relationship to the Account
 The Account should have master detail relationship to the Invoice.I want to know what is the difference between the two. They both look similar.
Can someone please help
