Stratification 1 to 1

Stratification 1 to 1 was created to deal with the frequent need of stratifying a database, but stating a 1-to-1 correspondence
(note: this is not for value intervales --in that case, use Categorize database)
Analyze the following example:
Say you have a database and a stratification table.
From the database, choose the Category column, as the stratification table was created based on this field.

The result of the operation is shown below:

If in addition you would have wanted to create a pivot table with the results, you only would have to check the corresponding
checkbox, and choose the column to be analyzed and the desired mathematical operation.

The result is shown in the following picture. You may modify the pivot table created, by dragging and dropping the appropriate fields.
