14.19: Understanding Domain Aggregation
Learning Outcomes
- Discuss domain aggregation
There are twelve aggregate functions that extract and group data from a larger data set.
- DSum
- DAvg
- DCount
- DLookup
- DMin and DMax
- DFirst and DLast
- DStDev
- DStDevP
- DVar
- DvarP
These functions all have the same structure:
FunctionName( “ [Field Name] “,” [Dataset Name] “, “[Criteria] “ )
FunctionName is the name of the domain aggregation function being invoked; Field Name refers to the field containing the data in question; DataSet Name refers to the table in play; and, Criteria limits the inclusion of data per the scope necessary.
These functions can provide everything from a total of the values listed to an average of those values to the standard deviation of the values listed. The Help menu has detailed information about the functions.
