some questions to implement my RFID w/r

hi, Im playing with a RFID reader writer,
playing with some sample code in windoz, that I would for sure want
need running on my BBXM,

the reader is USB connection that connects in windoz as serial port,
it comes with some drivers,
what would be a good start to get this drivers working?

the sample code comes in Delphi, would the BBXM run delphi?

what ISA (Instruction set architecture) uses the BB?, delphi works in
linux x86 AFAIK

what other option could be feasiable (for a noob like me!), to

drivers, communication,

Does the BB run SQLite? or other db SQL? (with usb hard drive)

hope this makes sense!

thank you!
