Examples of Database Functions
If you were a serious data analyst in the 1980s and the early 1990s, you
would have been enamored with the database functions. I personally used
@DSUM every hour of my work life for many years. It was one of the most
powerful weapons in any spreadsheet arsenal. Combined with a data table,
the DSUM, DMIN, DMAX, and DAVERAGE functions got a serious workout when
users performed data analysis in a spreadsheet.
Then, in 1993, Microsoft Excel added the pivot table to the Data menu in Excel.
Pivot tables changed everything. Those powerful database functions seemed
tired and worn out. Since that day in 1993, I had never used DSUM again until
I created the example described in the following section. As far as I knew, the
database functions had been living in a cave in South Carolina.
Maybe it is like the nostalgia of finding a box of photos of an old girlfriend,
but I realized that the database functions are still pretty powerful. Cus-
tomers whined enough to have Microsoft add AVERAGEIF to the COUNTIF
and SUMIF arsenal. This was unnecessary: Customers could have done this
easily by setting up a small criteria range and using DAVERAGE.
