 So, in the table for heroes, we use the `team_id` column to define a relationship to the *foreign* table for teams. Each value in the `team_id` column on the table with heroes will be the same value as the `id` column of one row in the table with teams.

 In fact, SQLite is perfectly capable of handling quite big applications. At some point you might want to migrate to a server-based database like <a href="https://www.postgresql.org/" class="external-link" target="_blank">PostgreSQL</a> (which is also free). But for now we'll stick to SQLite.
