What is the data source associated with an entity adapter ?
The data source associated with an entity adapter is the main database object used to retrieve and persist object’s data. This can be a table, a view or a stored procedure. Having a table you map to the columns, with a view you map to the fields and with a stored procedure you map to the arguments and/or the cursor fields. In case of a table or view, once defined the main data source you can defined other joined ones (Joined sources).
