Brandon Stout will cover this article:
http://dev.mysql.com/tech-resources/articles/hierarchical-data.html
And discuss how to use PHP's mysqli (MySQL Improved) extension to
connect to the database and retrieve the hierarchy in a list format,
like navigation menu on http://mscis.org . The presentation is MySQL
tiered, but one can apply the same basic concepts to other database
engines as well.
