REST service (100% Java)

erDiagram
    item {
        bigint id PK
        timestamp created_at
        varchar item_name
        enum item_type
        enum item_unit
        bigint discount_id FK
    }

 discount {
        bigint id PK
        enum discount_unit
        boolean is_constant_slab
    }

    discount_slab {
        bigint id PK
        double discount_amount
        bigint units_to_get_discount
        bigint discount_id FK
    }

    discount ||--|{ discount_slab : discount_id
    discount |o --|| item : discount_id

Documentation

All the endpoints and possible requests/exceptions are documented in Postman(and many of them in Javadoc). The requisitions are with fulfilled bodies and ready to be tested locally

How it works?

The DB

I have used H2 in memory db (100% Java), so if you want to take a look in the tables access /api/v1/h2 and you will have access to the console (credentials in the application.properties)

Enregistrement.de.l.ecran.2024-04-29.a.08.32.35.mov

Item's cheat sheet

Use these identifiers (default data) to interact with the API

ID	CREATED_AT	ITEM_NAME	ITEM_PRICE	ITEM_TYPE	ITEM_UNIT	DISCOUNT_ID
1	2024-04-24 10:00:00	Vegetables	0.01	VEGETABLES	GRAM	1
2	2024-04-24 11:00:00	Dutch Beer	0.5	BEERS	PIECE	2
3	2024-04-25 11:00:00	Bread	1.0	BREADS	PIECE	3
4	2024-04-24 11:00:00	Belgium Beer	0.75	BEERS	PIECE	4
5	2024-04-24 11:00:00	German Beer	1.0	BEERS	PIECE	5
