Summary

We've come to the end of an intense chapter. I hope you have followed the topics and, if not, I highly recommend to go back to read those sections which you found most difficult, so that you learn the concepts at full.

In this chapter, we have learned the importance of having a well-designed data architecture, how to load data from another QlikView document or previously loaded table in RAM, and also data aggregation functions and their uses.

We then learned how to order tables during load, how to calculate fields based on previously read records, how to deal with slowly changing dimensions to incorporate those tables into the associative data model, and finally the general process to perform an incremental load.

In the following chapter, we will continue exploring some front-end functionalities that can help us improve the user experience for our apps.
