11. BITS now

12. Non functional
Requirements

13. BITS now
Components
• Front end mobile application
• Background service
• Web server(Apache)
• Database server(MySQL)

14. BITS now
Background Service
• The UI thread(where user gives touch/text input to screen will run
independently of the background service.
• Background service is basically an AsyncTask.
• android.os.AsyncTask<Params, Progress, Result>
• This class allows to perform background operations and publish results on the
UI thread without having to manipulate threads and/or handlers.

15. BITS now
Background service
• Service is started once the client installs the application on a wireless device.
• The background service will always run, irrespective of whether application is
running/not running or phone is locked
• Even if phone is switched off, the service will automatically start once the
phone switches on(uses Broadcast Receivers).

System Interfaces
Development:
◦ IDE: Eclipse 3.7.2
◦ Java SDK 1.6
◦ Android SDK v20.0.2
Drawing Tools: ArgoUML

17. BITS now
User Interfaces
• Home screen: Grid view of all functions available. Each grid item consists of
an Image Button and corresponding title
• Most functional Activities(An activity is a single, focused thing that the user
can do) will be List views – student/faculty/course profile, contact lists, etc.
• Horizontal and vertical scroll bars will be used to support varying screen sizes

18. BITS now
Notifications
• Outside normal UI, reminders and updates
conveyed to user via notifications in the
status bar.
• For example, class cancellation
notification/broadcast messages.

19. BITS now
Hardware Interfaces
• Client Side: Wireless devices running with Wi-Fi/GPRS connectivity.
• Server Side: Remote machine hosting Apache web server – ability to receive
HTTP GET/POST requests.
• Central database server

20. BITS now
Software Interfaces
• Client Side: Android OS
• Server Side: Apache server hosts all PHP scripts which processes the requests
from the application front end.
• Database server: The PHP scripts interact with the MySQL server either on the
same machine/remote server.

21. BITS now
Security
• Username, passwords, and other private information cannot be extracted
from either the web server or front end application without authorization.
• Encryption of password(md5) before sending over network for authentication.

22. BITS now
Reliability
• The front end application will work perfectly even if network connection is
unstable(AsyncTask).
• Also, reliability depends a lot on the status of the central database
server(already in place). If the central database server is down, the
application might not work as expected, but all cached data will still be visible.

23. BITS now
Response
Response of application depends on 3 things:
◦ Responsiveness of client’s wireless device
◦ Network strength and quality
◦ Amount of network data download/upload
