Summary

In this chapter, we explored the inner workings of table calculations. We began by considering two questions:

  • What is the function?
  • How is the functions applied?

As we explored these two questions, we surveyed each unique group of table-calculation functions with the exception of the Script_ functions, which will be covered in Chapter 15, Programming Tool Integration. We also learned how to apply these functions to a view through partitioning and addressing.

In the next chapter, we will explore a new functionality: level-of-detail (LOD) calculations. We will discover how LOD calculations can easily accomplish tasks that were previously only possible through complex table calculations. It's important to note, however, that even though LOD calculations can, in some cases, replace table calculations, they by no means replace every instance of table calculations. Table...
