As well as contributing to the CAOS research practice here at The 451 Group I am also part of the information management team, with a focus on databases, data caching, CEP, and - from the start of this year - data warehousing.

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. What follows is a rough outline of the role open source has played in the sector. Any comments or corrections much appreciated:

All three of us announced today that Fox is running a massive production data warehouse built atop Greenplum's data warehousing software on Sun's Solaris/ZFS based OpenStorage platforms (a sea of Thumpers, to be specific). That is to say, open source software is at the core of one of the world's largest - and most affordable - data warehouses.

Until this week Infobright’s claim to open source fame was its partnership with MySQL that enabled its analytical data warehousing software to act as a storage engine for the open source database.

However, the company is now taking the open source route itself by releasing the code behind its Infobright data warehouse (formerly Brighthouse) as Infobright Community Edition.

Earlier this month the company announced that it was moving to a subscription model for the commercial version of the product, Infobright Enterprise Edition, which comes with “enhanced features, services and support, warranty” amongst other things.

The company has also announced a $10m Series C investment …

I?ve already taken a look at MySQL?s changing business model and the potential business drivers behind the company considering introducing new functionality under to Enterprise customers only. One area that I didn?t dive into was the impact on the company?s development model.

This, in fact, was the focus of Jeremy Cole?s initial take on the news as well as a significant response from Marten Mickos. ?MySQL will start offering some features (specifically ones related to online backups) only in MySQL Enterprise,? explained Jeremy.
