Data integration with ARDUINO

Hi all, I'm a new comer into arduino. Still at the basic stage in coding and electronics. My professor gave me an assignment to create a project of the following concept. I have no clue on how to proceed.

Please suggest steps on what components I need and basic flowchart for coding.

[u]DATABASE[/u] DATA1 | DATA2 |==> GENERATE UNIQUE BARCODE DATA3 |

SCAN BARCODE ==> Compare with data base if data matches blink LED Green else blink RED

I could really use someones help. I have no clue on how to proceed.
