Description

Since an author may have more than one webpage, a webpage table is necessary to map multiple webpages to a single author record.

• webpage_id - This column is the unique record id for the webpages table. It is the primary key for the table.

• author_id - This column is a foreign key which points to a record in the authors table.

• publisher_id - This column is a foreign key which points to a record in the publishers table.

• url - This column holds an author webpage address.
