HI All,I am working on a application using GWT and AppEngine (Java with datastore) , got stuck in design phase.
The application need to take input from barcode reader and will fill up some text boxes with information corresponding to the barcode. You can assume it to be a bookstore selling application which can fill up the book details like book name and price from the barcode when preparing the bill. Now my worries are: 1. As the information can change on server by admin the individual seller should be in sync with server. but it would be very time taking if for every barcode readed I send a request to server so I think we should store the information on client side and keep it in sync with the server as the changes are not expected to be very often. 2. If I keep all information on client side it is not possible to keep all barcodes information in memory as they can be in huge numbers may be millions, is there a effective way to keep all information on client side or any other way instead of storing it on client side. 3. Also i don't want my user to loose any information if there is any disruption in internet connectivity.so can i use something like a offline mode which will store all information locally if internet is not connected and as soon as connection is there it gets sync with server similar to java web start. I am beginner, it would be great if you guys can tell me about any others issues I should be aware of while developing such application with GWT and AppEngine.
