        Thanks a lot! Really some interesting information there, while I fear we really need something better founded... at least his assessment of IBM's "independent" assessment seems less biased than IBM's, but I'd still like some harder data.

> Other inline comments in large blue.

        Oh, that was it... people using HTML formatting to differentiate their answers, and this does not show corretly to lotsa clients -- for example, I'm (unfortunately) sitting behind Lotus Notes.

        This is not a fair assessment. IBM do have pre-SQL software they still support or even develop, and DB2 for the OS/390 is a different product -- but it is largerly compatible with DB2/UDB *and* is on a platform long abandoned by Oracle.

        Also, inside a product I gather the different editions of DB2 are *more* uniform than Oracle's, meaning you don't need to shell out more just to use that one feature you really need.

        That said, I do regret that DB2 ain't available on more platforms.

> "...DB2 for having a SINGLE index type and then having to

        This is an indictment of the paper in question, not an evaluation of DB2.

        This is a nice piece of information, but it is quite generic and outdated. Would love some up-to-date information on this.

        Here I've been seeing more and more functionality as PL/SQL stored procedures.

        Conceded. And more easily available demo and development copies too.
