This video covers aggregate design, which is a way to separate domain models and data for persistence. The presenter discusses how this can be done in an entity framework application, and how it can be beneficial for change tracking and state management.

  • 00:00:00 This video discusses how to separate persistence from domain models in an entity framework application. The presenter shows an example of how to create an aggregate route in an entity framework application by encapsulating the entity model in a class and using a repository to manage the data.
  • 00:05:00 In this video, aggregate (root) design is discussed, specifically how it can be used to separate behavior and data for persistence. A micro orm is used to illustrate how changes in the data model (e.g. adding or updating items) are tracked and saved to the repository. This is in contrast to a traditional orm, where changes are not tracked and the data model is directly written to the database. The benefits of aggregate (root) design are also mentioned, including the change tracking and the ability to use an orm without having to worry about state changes.
  • 00:10:00 In this video, the presenter describes how to use aggregate design to separate behavior and data for persistence. This allows you to track changes without needing to write event-based code.
