Dear, I am more than expert in android app development and integrating with servers/backend databases. One thing please clarify ... "each person's data record can have multiple tables;" does this means that user will create table using our app ? ..or our app will generate table automatically ?

Hi We have worked extensively with database and server related applications. Our last project on freelancer (Distributed systems) was on a similar concept and thus we have the required modules already in place and thus we can deliver the application pretty fast. The specifications are listed pretty much in detail and thus very clear. Could you please provide inputs to a few queries I have: 1. Each device will have only one user logged in forever, or a user can logout for another one to use the app on the same phone. 2. Is there an option to update the data on the server directly. A server portal or website? 3. Do you have the UI design in place? A few option we can further add to the app to add security: 1. Session based syncing to add security to the app 2. Second backup for the data to the backend, for further protection of data (optional) If you are fine with the proposal, We can discuss the prospect further on the chat. Looking forward to hear from you Regards Shweta

Hello, Thanks for providing sufficient information about functionality and it surely helped me to understand complete scope. Couple of ideas from my side; #1 Atomic synchronization: We can have atomic synchronization rather start sync whenever device tables update. It is better to have one point where all data gets synchronized. Doing so, we can maintain atomicity and will never miss any data. Your thought? #2 Why are we having different tables for each person? We can logically separate data rather having different hard to manage tables. As Sqlite is small and having it's own limitation, my advise is to use file system for saving video, images. Your advise? We have expertise in mobile and web development and therefore can assure you that it does not have much technical difficulty. However, I wish if you can provide me much detailed information for application like core concepts, information needed from person and so on.. Should you have any question, please feel free to send me message and I will back to you accordingly. Thanks Prakash
