- I used Hexgaonal architecture with Domain Driven Design
- Aggregate roots: Customer and Book
- Value objects: EuroMoney, CustomerId, BookId, LoyaltyPoints, Percentage, BookType's
- I used Joda Money to represent Customer balance and Book price but its wrapped with VO EuroMoney
- Using Swagger, Loggs and Unit tests
- As persistence layer i have H2 Database with Hibernate And Spring JPA
- There could be some refactoring of variable names, maybe even code design but as requirements are not fully defined i had freedom to design simple as possible
