Close to Home SystemHubAndroid AppModuleOnline DatabaseModuleModuleModuleWeb Server BasicsBridge the gap between app and hubUtilize web hosted programming to relay data from hub to app and commands from app to hubUtilize web hosted database to keep a live record of the various hub statuses

Web Hosted ProgrammingJavaStrongly typedRigid I/OMore SecureWeakly typedLoose I/OBetter Server SupportCross-Platform We are opting for PHP in order to help the system work together throughout the entire project and facilitate accessibility for the Hub and App.

DatabaseEmbed in deviceCan be tricky to keep synched with multiple usersEmbed on webCan handle multiple users simultaneously on the same database.

Server Design FundamentalsMySQLDesigned based on the class system of the hub based on specific roomsWill be updated by the hub and viewed by the Android app.PHPDesigned to handle I/O of data and commandsClass system to facilitate data sorting by class.
