Aggregate Data Connection

An aggregate data connection allows you to pull data from multiple tables like an SQL union operation would do. That is the data generated for the data definition would be the rows from multiple tables returned one after the other. The aggregate data connection is constructed from a list of other existing data definitions which must all have exactly the same parameters.
