+ *    "fields" => [
+ *        "<field name>" => [

+ *    ],
+ * ],
+ *
+ * Whenever possible prefer "foreign" before "relation" with the foreign keys.
+ * "foreign" adds true foreign keys on the database level, while "relation" is just an indicator of a table relation without any consequences
+ *
+ * If you need to make any change, make sure to increment the DB_UPDATE_VERSION constant value below.
