Hi. You should also have a look at Helical Insight. It is also an open source BI software. It is worlds first open BI tool with machine learning and NLP, allowing users to type their questions and get immediate business answers. It also has an inbuilt workflow functionality allowing to trigger any of the functional module of BI whenever you want, thus helping you implement any sort of business process. Also with a completely SOA driven archtiecture, the API allows to add functionalities at any layer (like data connection, charting, exporting, emailing, user role management, caching etc) without depending on the vendor. Coming from Open source BI background, I would request you to please do download and give it a try. http://www.helicalinsight.com http://www.helicalinsight.com
