2010 is officially the year of OBIEE integrating with Essbase, finally we are getting closer to one vision of true reporting--relational and OLAP sources married together in a way that actually works and makes sense.
BUT...OBIEE doesn't work super well with Essbase, it doesn't play together all that great in pre-11 OBIEE releases. I need to try out release 11 and see how well it integrates.
Maybe 2011 will be a better year for reporting integration. And, when are we going to see Reporting and Analytics integration? OBIEE and crystall ball all rolled up together--man, that would be sweet.
