Atlas is a data mapper implementation for your persistence model (not your domain model).
As such, Atlas uses the term "record" to indicate that its objects are not domain entities. Note that an Atlas record is a passive record, not an active record; it is disconnected from the database. Use Atlas records indirectly to populate your domain entities, or directly for simple data source interactions.
No migrations. No annotations. No lazy loading. No domain models. No data-type abstractions. No behaviors. No opinions. Just data source mapping.
