Summary
Relational databases are most widely used in the market for transactional work. Mastering one of the services with Azure SQL Database will give you the basis to implement other formats, such as Azure Database for PostgreSQL and MySQL.
In this chapter, we have looked at the connection of these databases in a simplified but sufficient way for you to start your projects and for the DP-900 certification questions.
In the next chapter, we will start Part 3 of this book, and Chapter 9, Exploring Non-Relational Data Offerings in Azure will explore non-relational databases on Azure.
