This chapter has been a very important one from a data loading point of view. As a QlikView developer, you should now have a great understanding of QVDs and why and how we should use them to implement an ETL approach. The folder structure model here will support an implementation from small business to enterprise.

We also looked at implementing really important techniques such as incremental load and partial load.

Finally, we had an introduction to Qlik's ETL tool, QlikView Expressor, and understand why it might be implemented instead of the QVD approach. There is a lot more to learn about Expressor and hopefully this introduction will spur you on to learn more about the product.

In the next chapter, we will learn about best practices around data governance in QlikView. We will also see more about Expressor's technology when we look in detail at the Governance Dashboard.
