Hi all, I have been working on back-end development for quite some time now, using mongoose/mongodb databases the entire time.
Now, I would like to work on my Sql skills aswell, but it’s not as clear to me where to start, compared to the mongo world.
People seem to use different management systems (postgresql, sqlite, mysql) and there is the option of using sequelize, which mongoose-like so you don’t have to write pure Sql.
So which direction should I go in order to call myself more or less fluent in Sql, let’s say for a job?
Do I need pure sql code or sequelize or both? Do I pick one management system (let’s say postgres) or doesn’t it matter that much? Is one more populare than the others nowadays?
As always, thanks in advance.
