There are a lot of similarities between a restaurant and a transactional database engine: they both have workers, performance can be improved with parallelism, and the fundamental ACID concepts are upheld by the waiters, menu, and the expediter in the kitchen. There’s going to be a little bit of “Sim-Restaurant” as we explore how changing the scale in both the “back of the house” and the “front of the house” can still be a problem if the door connecting them isn’t widened at the same time! Come join Michael Wall and Frank Geisler cover this introduction to transactional database theory using the fun analogy of a top-notch restaurant to explain each concept. Bring all your questions and you know there’s going to be servers and snacks!
