This presentation will cover how you can quickly and securely build Service Oriented Architectures using Drupal 7 Web Services.  There are three popular methods for doing this in Drupal using contributed modules (Services, Views data export, and RestWS). I'll mention the first two but show how and why I selected RestWS for the Services Oriented Architecture I'm building for our Drupal 7 implementation of ELMS. After this presentation you should know how to quickly build a Drupal site that also has a webservices component to it and see an example of how to build an end point for querying and consuming that information.
