I want to start an information provider service. It works this way: Some employees will find the information needed and fill a database manually. Users will request data they need on their client side apps on their own platforms. Some of the project specifications is as follows: 1) Data that will go between database server and clients is really small(Suppose some ordinary images). 2) The client side apps don't need to be kept updated. Once the user of app clicks update button(for example) the app will request the server to send required information. 3)It's important to run client side apps on several platforms like: windows, windows phone, android, ios,... 4) Database doesn't need to be vary fast or vary big.
Note: And It's important to note that I'm not expert and I have some limitations. I know java and html, css, javascript. But I think those are enough for this project. (Am I right?)
So I decided to design this development architecture: 1)Using hibernate and provide a layer for server which stands above hibernate and is used to do database-specific tasks. This layer provides some protocols for client side apps to communicate with server. It enables me to change database later without changing client side apps. 2)Using PhoneGap which is a framework that uses html, css, javascript and produces apps for many platforms. I really appreciate any suggestion, comment,... Thanks!
