There are two main ways to use the ORM: through automatic ORM properties, which automatically connects appropriately marked `DbArray` properties to the specified database, or by manually instantiating a `DbArray` with a `DbArrayBuilder`.

Classes extending `DbObject` have a special `save` method that can be used to persist object changes to the database, as can be seen in the [example](https://github.com/danog/AsyncOrm/blob/master/examples/2-manual.php).
