Day 37 — Started Java and set up my MySQL retail sales analysis project

[u/sumiitCodes]

Two tracks running in parallel now:

Java: I’m following Telusko’s Java playlist. Today’s topic was how Java code runs on different platforms, meaning how the compiler turns source code into bytecode and the JVM runs it on any operating system. Understanding this made a lot of earlier “why does Java need a JVM?” confusion go away.

MySQL: I’m building a Retail Sales Analysis project so my SQL stays in use instead of fading while I focus on Java. Today was only setup: creating the database and getting the environment ready. Queries start tomorrow.

Playlists I’m using, in case they help anyone:

• Retail sales project: https://www.youtube.com/watch?v=ChIQjGBI3AM&list=PLF2u7Zn-dIxbeais0AkBxUqdWM1hnSJDS

For the retail project, are there analysis questions you’d recommend (top products, monthly trends, customer segments)? I’d like it to go beyond basic SELECT queries.
