# Hierarchies & Child Objects

Sometimes you want to synchronize data outside of the current GameObject.

Out of the box, coherence offers you coherence offers you several options to synchronize data from your CoherenceSync objects' hierarchy:

* [Child GameObjects](/0.10/coherence-sdk-for-unity/networking-state-changes/hierarchies-and-child-objects/child-gameobjects.md): when you need to network data directly from other GameObjects.
* [Child CoherenceSyncs](/0.10/coherence-sdk-for-unity/networking-state-changes/hierarchies-and-child-objects/parent-child.md): when you create a parent-child relationship of CoherenceSync objects at runtime.
* [Deep Child CoherenceSyncs](/0.10/coherence-sdk-for-unity/networking-state-changes/hierarchies-and-child-objects/coherencenode.md): when you create a complex parent-child relationship of CoherenceSync objects at runtime.
