Top Priority/Metrics logic of the application #

I implemented a view counting system based on the user's viewing history.

Genre preference table #

Users have a preference table of genres, based on the movies they've seen that contain that genre.

This table is responsible for the order in which the genres will appear on the application's home screen. Genres with the highest numbers will appear first.

Most viewed genres on the Metrics View #

Each document that contains a respective genre contains a view counter that increments whenever a user watches a movie that contains that genre.

Documents with the highest counters will appear first in the metrics view.

Order of movies within the genre listing #

The document containing the movies also has a view counter. This counter is responsible for the order in which movies appear from left to right in the listings. This view counter is also responsible for the 'Top USA' on the metrics screen. Movies with the most views appear first.

Rank of users who watched the most movies #

This tank was built from the number of occurrences that this user has, as a foreign key, in the history document, saved in indexedb.
