Moneway

Version 1.0

This is an intern assessment for the position of a go developper at Moneway.

This is a simulation of a transaction and update of a balance. There are two services, "balance" and "transaction". The "balance" service is responsible for handling the balance within the database, and the "transaction" service is responsible for updating the balance (by contacting the balance service) and storing the transaction data.

These are the Features:

list the balance
Credit and debit an Account
Create transactions
Update the balance

The goal of the exercise is to apply (at most) the good practices of microservices (microservices.io and gRPC), the mastery of the Go language, and the mastery of database operations.

Database

This makes use of MySql Database

In the config/config.toml file you will find the configuration file for the Database. Make changes to suit your database settings.

  server = "docker.for.mac.localhost"
  port = "3306"
  database = "moneway"
  user = "your username"
  password = "your password"

The database schema could be found in the moneway.sql file.

Building and Running

In order to build and run code,open a terminal in the MonewayV1.0 Directory and execute the following command:

  docker-compose up --build

Making A Transaction

Structure of Transaction Object

  "transaction": {
        "AccountID" : "1", 
        "Description" : "This is a test", 
        "Amount" : 350.00, 
        "Currency" : "Euro", 
        "TransactionType" : "CREDIT"
  }

TransactionType can be either CREDIT or DEBIT

In order to make a Transaction Open a New terminal and run the following command:

  curl -XPOST http://localhost:8801/transct -d '{"transaction": {"AccountID" : "1", "Description" : "This is a test", "Amount" : 350.00, "Currency" : "Euro", "TransactionType" : "CREDIT"}}'

Future Works

In order for easy workflow within Moneway, we will be migrating to ScyllaDB.
