A New Framework for Data Management?

HubAndSpokeI hold a strong prejudice that IT paradigms are useful for about 30 years. The PC was dominant from 1980 to 2010, “online” mainframe systems from 1970 to 2000, and so on.

However, I’m pretty sure we’ll miss the relational model’s strengths in requirements definition and conceptual design. Continue reading

Special considerations in health care data

I’ve worked with health care data for the past few years, and in a recent conversation I realized it might be valuable to detail some of the complexities of health care data for those who might enter this growing field.  Of course these considerations aren’t unique to health care, but they are typical of the challenges that the new health care application developer or analyst might face.
