i want to create student attendance system for my final year project, i plan to use the barcode scanner as my input devices, any one here can give me the suggestion or tutorial for the system. i also have the problem in design database architecture for my system
there API's available for barcode reader there is java.comm framework which work with solaris/linux and for windows platforms there is api called RXTX though they dont process things for you , but they'll give basic utilities or I/O methods for you external I/O (barcode reader in this case)
for your data base architecture , i suggest you to be ready with all the Class Diagrams and Interaction Diagrams.. you automatically realize the DB Scemas you might be requiring.
