Since the start of this year I’ve been covering data warehousing as part of The 451 Group’s information management practice, adding to my ongoing coverage of databases, data caching, and CEP, and contributing to the CAOS research practice.
I’ve covered data warehousing before but taking a fresh look at this space in recent months it’s been fascinating to see the variety of technologies and strategies that vendors are applying to the data warehousing problem. It’s also been interesting to compare the role that open source has played in the data warehousing market, compared to the database market.
I’m preparing a major report on the data warehousing sector, for publication in the next couple of months. In preparartion for that I’ve published a rough outline of the role open source has played in the sector over on our CAOS Theory blog. Any comments or corrections much appreciated.
