Me doing a udemy course, hoping to find gap in my knowledge.

Hello there, me going through Udemy course here

Learnings so far

• Design the database for a simple bank project, (I added a users table, I'll adapt as the course goes)
• Using start and commit to ensure atomicity among multiple queries for a proper workflow
• Replicate a situation where deadlock might happened
• Learn how to mitigate deadlock
  • Example shows a situation where we want to update the balance of 2 accounts in one atomic transaction
• Setup a Go server
  • Currently the file structure in the repo are my own designs. (This part I'm not following the course, a good time to practice scaffolding a Go backend repo)
