QlikView - Dimensions and Measures

Dimensions and Measures are fundamental entities, which are always used in data analysis. For example, consider the result of the analysis, “what is the percentage change in volume of sales for each quarter?” In this case, each quarter represents the Dimensions, which is the name of the quarter. The percentage change in volume represents the Measures, which is a calculation with respect to each value in the dimension. Below are some widely accepted definition of these two terms.

  • Dimension − It is a descriptive field in the data set which represents few distinct values. Examples − Month, Year, Product ID etc.
  • Measures − It is a numeric field on which some calculations are performed for each distinct value of dimension.
