Well done! You've come up with the killer idea for 2019. You've got the best UI design anyone has ever seen! Your modern application ticks all the boxes—serverless, functional, Kubernetes, Kafka, microservices, API-based, the list goes on. It runs on every OS and every type of device.

Better data access typically means understanding how SQL is processed by the database, and who has time for that? SQL can be hard to understand and sometimes totally hidden from view under an ORM. Let's peel back the covers to show how SQL is processed, how to avoid getting hacked, and how to get data back to your application in a snappy fashion.
