Create, Read, Update, and Delete (CRUD) operations are the most basic database operations, but they are also the most crucial. CRUD operations are typically done using the Structured Query Language (SQL) on relational database systems. As the Web is becoming more and more data-oriented, there is a need to shift from SQL-based CRUD operations to semantic Web-based CRUD operations. Learn how to use PHP to perform CRUD operations over the semantic Web.

They include the SQL code for both sides (MySQL/SPARQL) on each of the CRUD steps. They take these and show how to plug them in to a PHP SQL call and briefly mention abstraction and a few reasons why you might want to move to SPARQL.

This is the fist time I have heard Rasmus Lerdorf speak and it was entertaining to say the least. Refreshing would another way to describe it, I enjoy hearing real opinions and not holding back - Rasmus doesn't hold back.

He talked about frameworks (and why they're not the best thing for the job), how you can make PHP fast (or can you?) and some mention of the semantic web and Drupal.
