Managing Connections In Power Pivot

Demonstrations that show importing data into Power Pivot do this from database icon in the home window (as identified below). However, once data is in your model and you wish to add new tables it is wiser to reuse the existing connection rather than create a new connection for each import. Each time that table(s) are added by this dialogue, a new connection is created within the model with multiple connections possible referring to the same source. For model simplicity, it is better to have a single connection referring to a single data source.
