Database First or Application First

Voice of the DBA

One of the challenges in software development is coordinating database and application changes when one depends on the other.

Plenty of you will either be developing those changes, or managing the systems to which those changes are deployed. You likely will be coordinating with other people (in either case) to deploy a software artifact (C#, Java, Python, etc.) and a set of database changes in order for your clients to use whatever new functionality is being delivered.
