Open source is ready for EDW. Because open source is designed to be modular, an enterprise can start with one piece - say ETL or reporting - and can add on as needed. For comparable power and features an open source solution in this arena can cost 10 to 20 times less than a proprietary product. Whether large or small, companies today are being asked to do more with less. With open source, you can have an EDW without compromise.
On Wednesday morning, June 12, I gave my paper on the three business rules projects to the ERBC: The projects were: Drools, OpenLexicon and OpenRules. It was well attended and well received. Pete Skangos and I gave everyone a copy of the book and we started an impromptu signing line, until it was a bit past the beginning of the next paper.
