UI components synchronize application state attributes with the AppStorage. Implementation of application business logic can access AppStorage as well.
Selected state attributes of AppStorage can be synched with different data sources or data sinks. Those data sources and sinks can be on a local or remote device, and have different capabilities, such as data persistence (see [PersistentStorage](arkts-persiststorage.md)). These data sources and sinks are implemented in the business logic, separate from the UI. Link those AppStorage attributes to [@StorageProp](#storageprop) and [@StorageLink](#storagelink) whose values should be kept until application re-start.

### Simple Type @Prop with Local Initialization and No Sync from Parent Component
To enable an \@Component decorated component to be reusable, \@Prop allows for optional local initialization. This makes the synchronization with a variable in the parent component a choice, rather than mandatory. Providing a data source in the parent component is optional only when local initialization is provided for the \@Prop decorated variable.
