+## Exercise
+
+1. Design a small REST API with GET and POST for orders
+
+2. Return a Customer fully populated with Orders → Items
+
+Complete the TODOs in order (lowest number first).
+You can use Lombok and Spring Boot 3 / Spring Data JPA.
+No DB scripts needed (use H2).
+Bonus points for validation & error handling.
+
+## What we’re evaluating
+
+[1–3] Entities & mappings: Correct One-to-Many with @JoinColumn, cascade, and orphan removal.
+
+[4–5] Repositories: Knows Spring Data basics.
+
+[6] Seeding: Can assemble nested aggregates and persist.
+
+[7–8] REST basics: Proper GET and POST, DTO usage, 201 Created with Location.
+
+[9] Nested fetch: Returns a Customer with Orders → Items (unidirectional makes JSON straightforward).
+
+## Read H2 data
+
+Open your browser at 👉 http://localhost:8080/h2-console
+
+In the login form:
+
+JDBC URL: `jdbc:h2:mem:testdb` (same as spring.datasource.url)
+
+User Name: `sa`
+
+Password: (empty)
+
+Click Connect → you’ll see your tables (`ZCUSTOMER`, `ZORDER`, `ZITEM`) and can run SQL queries.
+
+## Curl request
+
+### find all orders
+
+```
+curl --request GET \
+  --url http://localhost:8080/api/v1/orders
+```
+
+### find customer 1
+
+```
+curl --request GET \
+  --url http://localhost:8080/api/v1/customers/1
+```
+
+### add order
+
+```
+curl --request POST \
+  --url http://localhost:8080/api/v1/orders \
+  --header 'content-type: application/json' \
+  --data '{
+  "name": "office pack",
+  "items": [
+    "Pen",
+    "Notebook"
+  ]
+}'
+```
