I am building a custom application based on WordPress. I have my custom tables in the WP database. Can I use $wpdb to work with them, or is that class solely for the WP related tables?
For example, If I have a database that keeps up with dogs and cats, and I create a custom table named animals (animalid, animal_type, etc.). Do I use $wpdb?
I don't know if "interacting with the WordPress database" with $wpdb is intended solely for the stock tables or not.
EDIT: I created the tables by hand with MySQL Workbench. They were tables upsized from Microsoft Access. I have not "informed" WordPress of their existence or know if I should.
