# Atlas.Orm Atlas is a [data mapper](http://martinfowler.com/eaaCatalog/dataMapper.html) implementation for **persistence models** (*not* domain models). As such, Atlas uses the term "record" to indicate that its objects are *not* domain objects. Use Atlas records directly for simple data source interactions at first. As a domain model grows within the application, use Atlas records to populate domain objects. (Note that an Atlas record is a "passive" record, not an [active record](http://martinfowler.com/eaaCatalog/activeRecord.html). It is disconnected from the database.) Documentation is at .
