I do not know of any database that can help one find out what a "mystery" bike's identity might be, especially as lots of them are quite similar, and some of them just different only with the finish and graphics applied.
Best yet is to post pics of your bike on this forum to see if anyone can recognize it.
If anything, the members on this forum's knowledge and, memory is really the "database" you are looking for to properly identify your bike.
Regarding your bike, the components sound like lower level stuff you might see on an entry level bike,.....but the Campagnolo dropouts say good quality, so the components and frame described does not seem to match up.....
Pics of the bike will certainly help.
