class Book(models.Model):
title = models.CharField(max_length=200)
author = models.CharField(max_length=100)
publication_date = models.DateField()
```
*5. Views*
Handle HTTP requests and return responses.
```

from django.shortcuts import render
from .models import Book
def book_list(request):
books = Book.objects.all()
return render(request, 'book_list.html', {'books': books})
```

HTML files that display data.
```

<h1>Book List</h1>
<ul>
{% for book in books %}
<li>{{ book.title }} ({{ book.author }})</li>
{% endfor %}
</ul>
```
