Hi Fergus,
The idea here is that if you do not give a name to your data source, then it
is the 'default' data source and gets used automatically by all entities. If
you decide to give a name to the data source, then it should be specified
for each entity.
Even when you have multiple data sources, you can decide to give a name to
only one of them. The un-named one will be used for all entities which do
not have a dataSource attribute.
Hope that helps.
