Summary

In this chapter, you learned about the different types of LOD calculations. You learned how LOD calculations are executed internally, and saw how different components used in the view, such as filters, are executed, and how these affect the LOD calculation output.

The key benefit of LOD calculations is that they allow you to control aggregation levels in data without adding or removing components in the view. This can help identify trends at different levels of granularity within your dataset.

LOD calculations greatly enhance data analysis, and allow analysts to control the granularity of analysis or visualization. In the next chapter, you will combine all you have learned so far, and will begin to create storyboards and dashboards in Tableau.
