For the purpose of this tutorial, let's create a Greenhouse, Lane, Zone, Grid and combine Temperature Sensor from tutorial 1 to a particular zone.

DataModel to store non-thing related data

TQLEngine provides DataModel to store "pure" data, DataModels do not combine facets. They are simply models to store application data that is essential to create a meaningful real-world IoT application.

...

Greenhouse : Overall DataModel holder for Greenhouse. GHLanes is defined of type reference. There are two types of references - simple reference and smart reference. Smartness can be defined by providing a "Find" Query at the time of model definition or at the time of instantiating the model. GHLanes is defined as Reference to include all the Lanes from Lane model.
