Monolithic databases are so 20th Century. Today's teams pick the right tools for the job - a JSON document store or columnar database for scale, a graphing database to create connections, a message queue to handle messaging between services, a caching system to accelerate queries, a time-series database for streaming data, and/or a relational DB for metrics an more. Data Layer is to talk about them all, plus the application development around it. You'll find this event at the intersection of data and app development.
