Representing Calculated Values

As with any dataset, you can add calculated fields to your client dataset. These are fields whose values you calculate dynamically, usually based on the values of other fields in the same record. 

Client datasets, however, let you optimize when fields are calculated by using internally calculated fields

You can also tell client datasets to create calculated values that summarize the data in several records using maintained aggregates.
