The folks at webdetails have posted their Pentaho Community Dashboard Framework tutorials that look great! They run you through building CDF dashboards which is usually a crucial, user facing part of any BI implementations. While much of the work is the ETL/OLAP configuration, tuning, etc on the backend most users think of Pentaho as the dashboard/reports they interact with not the data munching for the Data Warehouse.
These tutorials look great; I’ve implemented more than 20 CDF dashboards at four customers already but I still bought them to learn even more ins and outs. You should too! No better way to learn something than from the source of the technology which in this case is Pedro and team @ webdetails.
