The Database Column is a new “multi-author blog on database technology and innovation.” What makes this a great resource is the amazing list of authors, which includes bigwigs from the age-old (sic) database industry like Michael Stonebraker, Jerry Held and Don Haderle from. (For those who do not know, Stonebraker and Held were the architects of INGRES and POSTGRES, the relational database management systems (RDBMSs) that started it all; Haderle was the architect of DB2.) Well known academics like Mitch Cherniack, David Dewitt, Samuel Madden, Stan Zdonik are also writing there.
This blog seems very promising. The first main post on the blog was almost proclaiming that the end of RDBMS is near and that the Column-Oriented DBMS is the next bug thing, at least for the Data Warehousing applications. (Note that Stonebraker is now the CTO of Vertica, a Column-Oriented DBMS company.) They followed it up with a couple of interesting posts on compression in Column-Oriented DBMSs.
