Hiya,
My apologies for neglecting this blog… The SSA CIO job takes time. I have several database-specific blogs drafted that I hope to get to over the holidays…
In the meantime here is a CIOish post on the problem of modernizing old IT infrastructure:

While it is not specifically about database infrastructure… I think that folks with database systems designed and developed over 20 years ago… maybe with schemas that are not subject-oriented or stuck on old or very proprietary database architecture… might see the thinking here to be relevant.
Finally, I want to wish you all a happy end to 2015… and to wish for you a happy 2016…
