An IOT system is illustrated in the figure below. As seen at the bottom of this system, data is collected from different sensors (temperature, humidity, pressure, etc). These data are transferred to the database with different communication methods. During data transfer, intermediate layers such as VIN (Veri Toplama Noktas) and VON (Veri Odak Noktas) are used. Collected data are also transferred to mobile devices via web services over the cloud system. Make the general database design of this system and draw the ER Diagram. Show the steps by explaining step by step the database you have created, passing through the normalization processes (by giving definitions and explaining normalization steps very clearly) a-the second normal form. b- the third normal form. C- the Boyce-Codd normal form.
