Summary

That brings a close to our fourth chapter. Congratulations on making it this far.

Just to recap, we started off with the basics of data modeling and learned about Star and Snowflake schemas. We then learned about designing for SCDs, the different sub-types of SCDs, dimensional hierarchies, handling temporal data by using time dimensions, loading data incrementally using ADF, and selecting the right analytical store based on the customer's requirements. Finally, we learned about creating metastores for Synapse and Azure Databricks. All these topics complete the syllabus for DP203 – Design the Serving Layer. You have now learned how to design your own Serving layer in Azure.

We have now come to the end of our design chapters. We will be focusing on the implementation details from the next chapter onward. Yay!
