Healthcare Data Models Matter

  • Article

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.

Question of the Day

Implementing Change Data Capture

I have a complex environment that uses quite a few SQL Server 2022 servers. We have a powerful SQL Server running Enterprise that hosts most of our transaction data. However, there are remote locations that run Standard, Web, Express, and Express with Advanced Services editions for local collection of data before the data is transferred to our central Enterprise Edition server. We are considering using Change Data Capture (CDC) to lower the amount of data we transfer from clients. Which editions can we implement this feature on?
