# Creating Book Process

### User Story
As a user, I want to be able to view information about books available in the library's collection. When I search for a specific book, the system should display details such as the book's title, author, genre, and availability status. If the book I'm searching for is not found, the system should provide a message indicating that the book is not available.

### Task

- [x] Implement Data Access Object (DAO) Layer.
- [x] Implement Service Layer.
- [x] Create JUnit Test Cases.
- [x] Ensure that the tests cases are passing.
- [x] Write clear and concise comments in the code to explain complex logic.

#### DAO
- getBookByTitle()

#### Service
- getBookByName()

#### Junit Test
- testValidGetBookByName()
- testInvalidGetBookByName()

### Estimation
- 3 hours
