There is a very big conceptual difference between the two.In case of tuple relational calculus ,you operate on each tuples but in case of domain relational calculus ,you deal with each column or attribute.Both methods can be used to get any result.
A tuple is a single element of a relation. In database terms, it is a row.

The tuple-oriented calculus uses a tuple variables i.e., variable whose only permitted values are tuples of that relation. E.g. QUELThe domain-oriented calculus has domain variables i.e., variables that range over the underlying domains instead of over relation. E.g. ILL, DEDUCE....The tuple-oriented calculus uses a tuple variables i.e., variable whose only permitted values are tuples of that relation.A domain is equivalent to a column data type and any constraints on the values of that data. For example the ‘First Name’ of a customer field would be character data and might have a restriction that it not be NULL.
