Communicates with the door, the microwave generator and glass spinner The incoming message is from the individual who is the user and also from the microwave door which tells if the generator if it is safe to be powered on Outgoing message tells the generator to start to create waves, spin the glass table and lastly to display information on the LED display screen Microwave Door
There is communication with the microwave door to make sure the device can only be operated when door is closed There are no incoming messages, if not specified from the user Outgoing message is given when the door is opened or closed. This tells the interface when the device is turning off if the microwave door is then opened Microwave power generator
Communication is with the interface incoming message is from the interface and dictates when the generator stops or starts wave generation. Outgoing messages to the interface to inform of current state Glass Table Spinner Communication is with the interface incoming messages are from the interface to tell when to start or stop spinning There are no outgoing messages.
One of the biggest advantages to having a componentized system is that is does not cripple an entire machine or operation.

The interest for the development of such systems stems from the need to cover the modeling deficiencies of their predecessors, that is the relational database management systems. They were intended to be ...
