Dataswitcher Tech Challenge

Goal

The objective for this challenge is to convert a small set of data from CSV format into a database, mapping the data according to the given specifications.

Read everything properly. Proper analysis of requirements and data is half the work.

Relevant Contents

data - folder containing the CSV files to read and convert

specs - specifications for the data format to store in database

src- all your code should be placed in this folder

tests- folder for the tests

convert.php - command to start the conversion

Instructions

1. Clone this repository and develop the solution in your own repository

2. Install Docker in your machine

3. Build and run the Docker instances with:

   docker-compose up -d --build

4. Wait for it...

5. After the instances are setup you can run commands using:

   docker-compose run --rm console <command>

6. Lets run composer update for example:

   docker-compose run --rm console composer update

7. Your code should be placed in the /src folder

8. Open converter.php and call your code there

9. You can run the converter with

   docker-compose run --rm console php convert.php

10. You can run tests with

    docker-compose run --rm console ./vendor/bin/phpunit tests

11. Monolog is available and logs are stored in app.log. Use it at will.

12. Good luck!

Requirements

1. Don't reinvent the wheel. Feel free to install whatever packages you might require.

2. Use an ORM or ODM to access Mongodb.

   We recommend Xenus but choose your prefered one from:

   https://docs.mongodb.com/drivers/php-libraries/

3. Be pragmatic in your approach while keeping an eye on SOLID principles.

4. Without over engineering use OOP best practices to organize your code (interfaces, abstracts, models, etc).

5. Write at least some basic unit tests for your solution.

6. Only map data that is directly available on target, skipping all that is unneeded.

7. Challenge is complete if we see all data correctly stored in Mongodb collections according to the specs

Bonus

The following is OPTIONAL but will be highly valued in your application

1. Change the type of transactions that are invoices. Feel free to explore the data to find that info.

2. Add the current balance to the accounts. Feel free to explore the data to find that info.

OTHER INFO
