This document summarizes Kevin Haag's presentation about event-driven data layers and Adobe Analytics. It discusses different types of data layers including the event-driven data layer (EDDL) and customer experience digital data layer (CEDDL). It also describes how Adobe products like Launch and DTM previously did not have a built-in data layer model, but now the Data Layer Manager extension allows populating custom variables and triggering rules based on data layer events. Resources for learning more about data layers and analytics are also provided.
