When we published our 2008 report on the impact of open source on the database market the overall conclusion was that adoption had been widespread but shallow.

Since then we’ve seen increased adoption of open source software, as well as the acquisition of MySQL by Oracle. Perhaps the most significant shift in the market since early 2008 has been the explosion in the number of open source database and data management projects, including the various NoSQL data stores, and of course Hadoop and its associated projects.

On Tuesday, November 9, 2010 at 11:00 am EST I’ll be joining Robin Schumacher, Director of Product Strategy from EnterpriseDB to present a webinar on navigating the changing landscape of open source databases.

Among the topics to be discussed are:

· the needs of organizations with hybrid mixed-workload environments

· how to choose the right tool for the job

· the involvement of user corporations (for better or for worse) in open source projects today.

You can find further details about the event and register here.

In addition to the 451 Group’s own data warehousing webinar on Thursday I will also be taking part in a webinar on Wednesday with EnterpriseDB on the subject of open source database adoption in the enterprise.

During the webinar we will provide recommendations for how organizations can effectively leverage open source software. Attendees will learn about open source software trends for 2010, top considerations when using open source databases, and best practices for successful deployments of open source software.

I’ll be providing some data points from our recent surveys on database adoption and open source adoption while EnterpriseDB’s Larry Alston will also showcase successful enterprise deployments of Postgres Plus.

The open source database webinar is Wednesday, December 16, at 1 pm ET. To register, visit this link.
