or, the “JOIN me for some fun” part.

i don’t have too many things to comment on as far as databases go. they’re probably my weakest area. (i’m open to suggestions!)


  • PostgreSQL: Recommendation used to be MySQL but PostgreSQL has definitely taken off community-wise.
    • a great service that provides Postgres as a service is Supabase.
  • Postico: you might have grown up on phpMyAdmin 🤮. this is better.


prisma is a simple layer to have your code interface with your db.

on the other hand, there are arguments against using ORM’s since they can add cruft to your queries. as mentioned in the JS section about using frameworks, in general, using a higher-level wrapper doesn’t excuse you from learning how the underlying technologies works!


  • in your source code, a folder containing the scripts for updating schema from version 1 to your current version is recommended. (a tool for this would be great here!)
  • gh-ost. for more complicated db migrations.

quick note on NoSQL

again, i’m ill-equipped to talk about db’s. but here are some options on NoSQL to explore if you’re into that kind of thing:

useful commands

(further reference on commands here.)

for when you can’t use the GUI and have to use the command line.

  • show databases — like it says.
  • use [database] — enter the context of a particular database.
  • describe [table] — show the structure of a table.
  • show create table [table] — show how a table is created. useful to get foreign key info.
  • select * from [table] where [conditions] — select columns in a table.
  • insert into [table] ('[column1]', '[column2]') values ('[value1]', '[value2]') — insert data into a table.
  • delete from [table] where [conditions] — to remove rows in a table.
  • exit — leave the program.
