Design

The model / database structure is composed out of Order, Customer, Specification and Pizza. The Order has a one-on-one relation with the Customer, the Order has a many-to-many relationship with Pizza through Specification. This way the order can be composed of whatever is specified in the Pizza database and the quantity and size are attributes of Specification.

Requirements

• docker

Installation

docker-compose build
docker-compose up
