b. Now you need to decompose the Order clothes process only. Forward order takes orders from the customer and sends that information to generate bills and update inventory process. Generate bill process generates bill based on the order and Inventory is updated by update inventory process. Design level-2 DFD for order cloth process and make sure it is Balanced. Also mention if you find any error in the scenario. Total marks 10 3. "HomeStar" is a home automation system to manage, operate and maintain household devices. Upon receiving command "Prepare workspace Prepare Homestar module is initiated. First Generate parameters module is given a dayight status and it returns the parameter details for the status as well as an optimization control flag for system optimization to be carried out later. Prepare HomeStar sends the parameter details to Prepare batch module and receives a list of activated devices in return. In order to prepare all connected target devices. Prepare batch module fetches a list of target devices from Get devices module by providing the parameters. For each device. Prepare batch module first calls upon Get current status library module providing the device id and in return receives whether the device is currently activated or not. If the device is not active, Activate device module is triggered using device id and parameter mapping. Otherwise Update device state module is triggered with similar information and the target device is updated with given parameters. After each device is activated/updated, Generate activation entry module creates formatted specification and returns an entry to Prepare batch. After all target devices are activated/updated, Prepare batch module sends the activated device list to Prepare HomeStar. Finally Prepare HomeStar Initiates the Optimize system module which is an off-page connector and initiate emergency alert module which is an on-page connector Design a structure chart based on the above information.
