I plan to develop a software application which requires a) recording of measurements arriving over a usb line (said usb line plugged into a measurement hardware device) b) analysis of such numbers and displaying graphs.
This data analysis will be per human being "subject", so we need also to have user accounts, database to store past measurements etc.
Ideally this would be cross platform (well, at least Windows and Mac).
As you can tell, I'm a beginner here. On the one hand, we want practicality and fast development, on the other, we want expandability and modern design.
