Hi all, 
I need some advices about the schema to adopt for an application that 
manages a certain amount of data coming from remote sensors (IoT).
My doubt is about the relation between a sensor and the many measures it 
produces (i.e. temperature=10, timestamp=1234567890).
I would be asked to satistfy a query like: give me the average value of all 
the temperature sensors in a specific time interval) and give me the last 
measure of the sensor xyz.
What's the most efficient way to implement the relation on OrientDB 
regarding the above scenarios (queries)?  
Thank you
ny
