Comparing value from Oracle DB to input from DMM

Ok so a quick synopsis of what I am doing. I would like to establish a connection with an Oracle DB Server, and query for a nominal resistance value based on an input from a usb barcode scanner. Then compare that value to an input from a DMM with RS232 output.

I have the scanner and an Uno right now. The DMM, ethernet shield, and rs232 shield should be in by the end of the week. I have downloaded the mySQL ide and would like to know if this is compatible with an Oracle DB. I haven't attempted the connection yet. I need to do some more learning first.

I understand this is several projects in one, but I am pretty confident in my ability to get a reading from the DMM into the arduino. I am mostly interested in querying the DB for a value and having some way to verify that value(perhaps a lcd readout with the nominal and the tested).

Any guidance on this would be much appreciated. Any experience with an Oracle or SQL connection would help a ton. Thanks.
