A Pig relation is a bag of tuples. A Pig relation is similar to a table in a relational database, where the tuples in the bag correspond to the rows in a table. Unlike a relational table, however, Pig relations don’t require that every tuple contain the same number of fields or that the fields in the same position (column) have the same type.
