Martin Snyder: Live coding a CRUD database in Scala

Food sponsor: Wingspan

Follow the live construction of an in-memory CRUD database complete with constraints and transactions. This presentation details fundamental concepts of database design and implementation and demonstrates how functional programming can produce rich functionality in a concise codebase. A reference implementation is available for download for participants who wish to follow along or examine things more closely on their own.

All code is written in Scala, using no external libraries, unless you want to count ScalaTest. Depending on the stamina of the audience, the final code ends up being in the 250-500 line range.

Attendees will leave this talk with a stronger understanding of how databases work, firmer grounding in applied functional programming principles, and insight into the rationale for developing something of this nature in today's world.
