Simple Bank

This repository contains the codes of the Backend master class course by TECH SCHOOL.

In this backend master class, we’re going to learn everything about how to design, develop, and deploy a complete backend system from scratch using PostgreSQL, Golang and Docker.

Simple bank service

The service that we’re going to build is a simple bank. It will provide APIs for the frontend to do following things:

1. Create and manage bank accounts, which are composed of owner’s name, balance, and currency.
2. Record all balance changes to each of the account. So every time some money is added to or subtracted from the account, an account entry record will be created.
3. Perform a money transfer between 2 accounts. This should happen within a transaction, so that either both accounts’ balance are updated successfully or none of them are.
