Zuyd Hogeschool - Design Research Casus

Introduction

This repository contains the code of a 10-week Design Science Research project, developed by students of the ICT faculty of Zuyd University of Applied Sciences.

The prime goal of this project was developing a 'tool' which would allow users to configure decision tree's (from now on called 'graphs')¹. These graphs could then be used by other users to interactively support their decision-making based on the configured structure. This and many other features have been implemented.

¹Formally the decision supporting charts are graphs, since multiple edges are allowed on the output as well as on the input of a node. This as opposed to trees, where each node can only have one input.

Deployment

For deployment and troubleshooting it is recommended to follow Laravel 8's documentation.

However, the most significant and moreover specific configuration tasks have been documented below.

Requirements

Next to Laravel 8's server requirements it is required to have one supported database which can be used by the application.

Installation

1. Clone this repository
2. Install composer's dependencies with composer install
3. Install npm dependencies with npm install
4. Configure the .env file in the repository.
   • If the .env file does not exist; copy .env.example file to .env
5. Generate application key with php artisan key:generate

Initialize database structure

Run migrations with php artisan migrate:fresh --seed

• Note: this command also executes the default database seed which includes the default node-types which can be used to construct graphs. These default types can be modified and extended in the file database/seeders/DefaultNodeTypeSeeder.php
• Note: for demonstration purposes it is also possible to include one example graph and one test user in the seeding process. To enable this, uncomment TestDataSeeder in the database/seeders/DatabaseSeeder.php file

Run

For development, the server can quickly be launched with Laravel's internal server using: php artisan serve.

Alternatively it is possible to serve the application by using another web server like Nginx or Apache. Please refer to Laravel 8's documentation for further reference.
