* A CalculatedDataElement (CDE) is created for a set of other related
34
* DataElements. Each constituent DataElement may be multiplied with a factor.
36
* An example: A value for the CDE "Number of births" is summed together from
37
* two other Data Elements, "Number of still births" and "Number of live
40
* CDEs may be displayed as subtotals in a data entry form. The user may specify
41
* whether or not the calculated value should be stored in the database. In all
42
* other cases, a CDE behaves just like any other DataElement.
