i need answer for iii), iv) and v)...

Your client wants you to develop a Mobile Application (App) to monitor a laboratory's safety remotely. The requirement for the App is stated in Figure 1. There are several things that you need to consider while planning for the App development such as the technical and architectural design consideration. (i) Explain THREE (3) primary technical consideration that you should address while planning the App design. There are several taxonomies of architectural styles that you can consider while planning the App design. Explain THREE (3) architectural styles. Then, decide which style that is suitable for this project. Justify your answer. (iii) Draw the Architectural Context Diagram for the Monitoring System. (iv) Then, develop an Activity Diagram of the App for the user to access the camera surveillance function. Finally, develop a Swimlane Diagrams from the Activity Diagram in (iv). 125 Marks "The Mobile Application must be secured. Only authorized personnel can use it. There are several sensors are added to the system for autonomous monitoring such as Passive Infra-Red (PIR) sensor, Smoke Sensor and Li- SOCI: (lithium thionyl chloride) Gas Sensor. There are also IP-Camera installed in the monitoring system. All data is stored in cloud database and can be accessed by the user from the Mobile Application. User are not only being notified if any problem happens in the lab but they are also can view the lab condition through the IP-Camera both in real-time and the historical footage."
