The focus of this hour was to familiarize you with the Django database-abstraction API. You got a chance to create some objects in the database. Then you learned how to access the objects through the database abstraction API using the get() and all() functions. You also learned about QuerySet and how to use the filter() and exclude() functions to perform queries on objects.
Throughout the rest of the book, you will get more experience accessing the database as more complex views are created.
