Want to keep a track of the availability of vacant/occupied rooms in selected list of buildings registered with the App. When we select a particular location through MAP the list of current occupancy/availability should be shown and be able to book if available for few hours or days. Ability to maintain current status of the rooms in each building by immediate update when status change. for example if I select a school in a particular city the application need to show the number of rooms vacant and available to book in each nearby building with floor no and room no. with few room features and class of room, and be able to book the room with mobile, and pay online. further the app should show the availability by each floor in the building. the mobile user also need to be registered with the App., use GPS to go to the location of the building/room. Database driven app with fully functional source code must be delivered with technical manual.
