For example, we may want to combine two tables together, or skip over a part of a script if a condition is not met.
It is important to note that QlikView script is executed in a sequential order. This means that script is executed top to bottom, and left to right.
In Chapter 3, Seeing is Believing, we started building a small QlikView document to analyze airline operations data. We loaded a fact table and some dimension tables. All this data was loaded from QVD files, without any need for modifications. Of course, this is a scenario that you are not likely to encounter in the real world. In this example we will look at a scenario that is a little more plausible, l focusing on the Aircraft Type dimension. Instead of a single, tidy Aircraft dimension...
