The Group statement collects various records with the same key and groups the data in one or more relations.
Example : Group_data = GROUP Relation_name BY AGE
The Order statement is used to display the contents of relation in sorted order based on one or more fields.
Example : Relation_2 = ORDER Relation_name1 BY (ASC|DSC)

Example : Relation_2 = DISTINCT Relation_name1
