Ok, so someone is going to take me to task for calling it a 'tutorial' because the correct term to use is "OBE" - Oracle By Example. To quote from the Oracle documentation site, "Oracle by Example (OBE) tutorials provide hands-on, step-by-step instructions on how to implement various technology solutions to business problems. OBE solutions are built for practical real-world situations, allowing you to gain valuable hands-on experience as well as use the presented solutions as the foundation for production implementation, dramatically reducing time to deployment."
There are two OBEs for the BI EE 10.1.3 release that are immediately available, while more are in the works.
For those of you who look at the URL closely, especially the OBE on Answers, it shall tell you a little bit of the lingering traces of the product's lineage :-)
