The examples in the previous sections show us what we can call procedural SQL processing. We've eschewed any object-oriented design from our problem domain objects. Rather than working with the Blog and Post objects, we're working with the data elements that SQLite can process string, date, float, and integer values. We've used mostly procedural-style programming.
We can see that a series of queries can be done to locate a blog, all posts that are part of the blog, and all tags that are associated with a post associated with a blog. The processing to retrieve a complete blog, all posts, and all tags on the posts would look like the following code:
query_blog_by_title = """
SELECT * FROM blog WHERE title=?
"""
query_post_by_blog_id = """
SELECT * FROM post WHERE blog_id=?
"...
