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.
