 ## Data Type Mapping
 
+Lance internally stores data in Arrow format.
 When integrating with Lance, Fluss automatically converts between Fluss data types and Lance data types.  
 The following table shows the mapping between [Fluss data types](table-design/data-types.md) and Lance data types:
 
-| Fluss Data Type               | Lance Data Type               |
