Object Model
An object model refers to digitizing an entity in a physical space and building a data model of that entity in the cloud. In an IoT platform, the definition model defines the product function. When the functional definition is complete, the system automatically generates an inventory model of the product. models describe what a product is and what it can do. The property model enables the rapid deployment of the business by defining a set of property templates for the device.
