Clone() used to copy only the structure.but copy() used to copy the both structure and data.

2. The DataSet class's Relations property contains a RelationsCollection object, which maintains a collection of DataRelation objects. Each DataRelation object represents a parent/child relationship between two tables in the DataSet.For example, there is conceptually a parent/child relationship between a Customers table and an Orders table
ds.Relations.Add("CustomerOrders", Parent column,Child column)
