Day 86 of 100 Days of Code & Scrum: SELECT Within SELECT, Aggregate Functions In SQL, and Other Stuff

Greetings, everyone!

Today, I worked on a lot of different things. I made some progress with learning SQL and Next.js as well as coding the Terms of Use page for my business site. Not too bad I'd say.

Note: The character in the thumbnail is Lena from 86.

Anyway, let's move on to my daily report!

Yesterday

I set my goals for this week, which are:

• finish the Terms of Use and Privacy Policy pages, and then deploy them.
• learning more SQL, Next.js, and Scrum.

Today

Next.js

• learned how to render markdown as JSX.
• continued going through Next.js & React by Maximilian Schwarzmüller.

SQL

• practice doing nested SELECTs.
• learn more about how correlated subqueries work.
• learned how to use aggregate functions, SUM and COUNT.
• continued to go through SQLZoo's SQL Tutorial.

Scrum

• read this article, titled Myth 3: In Scrum, releases are done only at the end of the Sprint by Barry Overeem.
• it is okay to release updates to production even before the Sprint Review.
• it is recommended to keep expanding the Definition of Done (DoD).

Thank you for reading! Have a good day!
