Healthcare Data Models Matter

Healthcare applications come and go, but data live on forever. We’ve seen that since the beginning of the computer industry; when we move from legacy systems into more “modern” architectures, we often leave behind applications, but we almost always take along the data into the future. Even though data are so important, we in health-IT don’t seem to spend the quality time necessary to structure our schemas and databases in such a way as to make it easier to maintain in the future. We often don’t design our data models solidly, and we don’t test them well by putting them through simulations or design them for multiple versions.

You may be wonderfully up-to-date with an AJAX Web interface or the latest whizbang Windows user interface, but under the covers, you're probably still pumping data in and out of a database, just as we all did a decade or more ago. That makes it all the more surprising that developers are still making the same database mistakes that date back to those good old days of Windows 95 and before.
