Anyone know what this does?

It's a database... It holds data.

Ya but how does it work?

with regards to what? are you asking how you use it? it's a relational model and you can use sql.

if you wanna know the inner workings, i have good news. it's open source. https://www.postgresql.org/docs/devel/static/git.html

Storing large quantities of numbers and outputting usable data into categories to interpret the numbers

For example:
Marathon splits
Poker hands
Late minutes
Weight gain/loss

so you're asking how to use sql? that's progress. you can look up tutorials on how to use sql (create table, insert, select). what kind of analysis are you trying to do? how much data are we talking about; hundreds, millions, trillions of data points? i assume you have some other language (eg: python) you're going to use to "interpret" the data?

It`s just a database management system like many others (from an external standpoint)
Learning how it actually works is like understanding how the brain of an archivist works when he`s on duty, won`t really help with your needs given the kind of questions made here. What you need is to have and make use of an archive (db), not understand the deep logic beneath.

Structured Query Language (SQL) is a standard for storing data in individual tables and linking them together based on shared attributes. PostgreSQL is a database that uses the SQL standard. To learn how to use Postgres you will need to learn SQL.

I have a access to stata v14 license if needed, pm me. (assuming you need to crunch an insane amount of obs.)

however I'm assuming you know what parameters to sort it by, not a programmer so unsure what SQL is about.
