Python SEO Shelves for a No-Database Database

In my previous video I used a Python decorator cache function to eliminate the immediate need for a explicit database to store the SEO SERP-data I was fetching and subsequent site-crawling data. In this video I add a bit more formal of a database than just the cache to store the data locally. It could be back-ended by larger databases, but I will for now trust the default behavior of the Python standard library shelve package. It can put off the need for a more formal database indefinitely. Combined with a decorator cache, you have an extremely good recipe for great object-persistence and database-like benefits without all the technical overhead and liability of a more formal database. Even SQLlite will make you have to think about table-structure.
