At the Information Difference we continue to add new research on the MDM vendors. One of the things that is useful to know about vendors when drawing up a shortlist is which platforms the various vendors support e.g. which database, which web server, and perhaps more minor but useful technical information about whether they have double byte character support, do they have 7 x 24 helpline support etc.
There doesn’t seem to be a place where this kind of information is gathered together but there is now.
This also has information on the level of SOA support (if any), which non-English languages are supported in the user interface etc.
