Summary

In this chapter, we covered how to define useful data quality rules, with a tightly defined scope to avoid false positives. We also outlined all the key features of data quality rules in order to explain what information must be captured to document a useful data quality rule design.

We now understand the process that is required to design, develop, and test data quality rules and how good leadership can make a real difference in these technical phases of our work.

Now that we understand the end-to-end process of creating data quality rules, it is time to move on to how the results that these rules produce are presented to stakeholders.
