There are physical tables and logical tables, and they are very different things.

You were talking about logical tables, The tables at the SQL level.

Physical tables as their name suggests, are at the physical level of the database. A level hidden to the users by the DBMS.

Logical tables don't necessarily map to physical tables and vice versa. This is called physical independence.
