I agree. We're storing more and more data, but that's also spread across a variety of database systems and architectures. Some databases are more sensitive about normalization (for optimization) than others, but it's definitely not a required rule. I think it's going to depend on the data, queries, and use case (and somewhat on the database involved). Thanks for your thoughtful comment! :)

Good point on the line numbers. I'll get that updated!
For something more complex such as testing against multiple databases, I would recommend using a devoted library such as TestContainers or Test Harness (mentioned in the last section of the post). That way (in Testcontainers, at least), you can spin up instances of each database in the test class, and run each test against the desired database. As a side note, using a different database for production than in development - I commend your bravery and daring! :D
