Hey,

In pig, Relation represents a complete database. A Relation is a bag or we can say a relation is a bag of tuples. As compared to RDBMS, a relation is a table, whereas the tuples are correspondence to the rows in the table. Tuples in a pig does not require to contain the same number of fields and fields in the same position have the same data type
