Calculation fields are used to perform mathematical operations on the selected data. The age, time spent, and distance are calculated from the static fields. A view is created with the fields necessary for the calculation and a column with the result is added. The virtual field does not create a complete view, but only two columns: the primary key and the field with the result. Then the field is attached to the entity. An additional plus: painless removal and addition of columns. The view will have to be created again.
