Small project that generates a recipe database given a YML file.

Intro to Database Systems - Project Phase 3

Project Name: Recipe Database – Explore recipes using ingredients.

Objective:

1. Generate a SQL Database, and insert all recipes found inside our .yml file.
2. Modify the Database such that we can SELECT recipes based on ingredient_name(s)

Generate database

1. Install docker
2. Navigate to the projects current working directory, and enter: docker compose up -d
3. To view generated data, see the instructions below.

---

To enter our database inside the container:

1. Find container_id of db container with docker ps
2. Enter container with docker exec -it <container_id> bash
3. Enter into the PostgreSQL command line psql -U user -d mydatabase

To generate the database .sql file:

1. Find container_id of db container with docker ps
2. Generate the .sql file with docker exec -it <container_id> pg_dump -U user -d mydatabase > mydatabase.sql

To select a recipe that uses an ingredient:

SELECT recipe.recipe_id, recipe.recipe_name FROM recipe JOIN quantity ON recipe.recipe_id = quantity.recipe_id JOIN ingredient ON quantity.ingredient_id = ingredient.ingredient_id WHERE ingredient.ingredient_name = 'INGREDIENT_NAME';

Example - Select all recipes containing 'Onions':

SELECT recipe.recipe_id, recipe.recipe_name FROM recipe JOIN quantity ON recipe.recipe_id = quantity.recipe_id JOIN ingredient ON quantity.ingredient_id = ingredient.ingredient_id WHERE ingredient.ingredient_name = 'Onion';
