documentation tool using the
sakila database as
an example. This is a sample database provided by MySQL that you can
find by visiting the http://dev.mysql.com/doc/ page, selecting
Other Docs tab, and looking in the
Example Databases section
An EER diagram is an invaluable aid to a quick understanding of any database. There is no need to read through table definition statements; glancing at an EER diagram can immediately indicate that various tables are related.
You can also see how tables are related; what the foreign keys are and what the nature of the relationship is.
