The Ioto Cloud Manager leverages the Ioto agent database schema to define what device specific data should be stored in the cloud and what are the device manageable entities.
The schema describes the device entities and their data properties and data types. From this, the Ioto Manager is able to dynamically construct a user interface when guided by the Display.json file.
See Database Schemas for details. Also read Database Replication for how to control data replication to and from the cloud.
