If you want to make your development team squirm, ask them about database schema changes or API versioning. Most development teams struggle with changing database schemas and updating API versions without breaking existing code. Alex Rasmussen is an expert in helping teams through these struggles. His talk will examine database schema changes and API versioning as two instances of schema evolution: how your systems respond when the structure of your structured data changes.
