Hi there..
RFID reader is interfaced with Arduino, I wanna use more than 50 RFID tags.. For each tag IDs, I wanna assign several details such like Item No, Name, Weight, Price.. I can create a database using Oracle or MySQL to have the details as I mentioned above of specific RFID tag's IDs. My question is, When I read the a tag using RFID Reader, how can I connect to database and access the specific details of the tag in the serial terminal or any other windows apps like VB or Java based? Please help who have the idea of this.. 
You won't be running Oracle on your Arduino, so I gather a PC is involved somewhere?
Why do you think asking the same question five times is a good idea?
Yes I want to create the database in PC but the problem is, when a tag read from the reader, the specific details from the database to the corresponding ID should be displayed in the GUI whtever VB or Java based.. so how can I do this.. im so much confused
Don't try to take this thread into personal messages, thanks.
